Having a similar issue
idx = date_range('2014-10-08 00:00','2014-10-09 00:00', freq='D', tz='Europe/Berlin')
pd.Series(5, idx).resample('MS')
ValueError: Values falls after last bin
While if I remove the tz :
idx = date_range('2014-10-08 00:00','2014-10-09 00:00', freq='D')
pd.Series(5, idx).resample('MS')
that works perfectly

``` python
import pandas
def main():
x = pandas.Series([0, 1, 2])
print(x)
if __name__ == "__main__":
main()
```
and use the default `setup.py`:
``` python
from setuptools import setup
import py2app
setup(
app=['main.py'],
options={'py2app': {'argv_emulation': True}},
setup_requires=['py2app'],
)
```
and run `python3 setup.py py2app` to build the .app and then start the application (Please note the example can only be runned via Terminal, since it lacks a GUI)
In both Python 2.7.8 and 3.4.2 the .app builds fine but fails on 3.4.2 to start and dumps (stripped to the helpful parts):
```
'module' object has no attribute '__pyx_capi__'

If the example would run as expected it would print (again stripped):

I can save the panel when using the fixed format (although I get a PerformanceWarning), but it fails for the table format. Example code:
``` python
import pandas as pd
import numpy as np
d1 = pd.DataFrame({1:pd.Series(np.random.randn(10)), 2:pd.Series(np.random.randn(10))})
d2 = pd.DataFrame({1:pd.Series(np.random.randn(10)), 2:pd.Series(np.random.randn(10))})
good_panel = pd.Panel({'a':d1, 'b':d2})
print good_panel
with pd.get_store('/tmp/goodstore.h5', mode='w') as store:
store.put('/test', good_panel, 'table', append=False)
b1 = pd.DataFrame({1:pd.Series(np.random.randn(10)), 'a':pd.Series(np.random.randn(10))})
b2 = pd.DataFrame({1:pd.Series(np.random.randn(10)), 'a':pd.Series(np.random.randn(10))})
bad_panel = pd.Panel({'a':b1, 'b':b2})
print bad_panel
with pd.get_store('/tmp/badstore.h5', mode='w') as store:
store.put('/test', bad_panel, 'fixed', append=False)
print 'saved as fixed'
with pd.get_store('/tmp/badstore.h5', mode='w') as store:
store.put('/test', bad_panel, 'table', append=False)

```
import pandas as pd
df = pd.DataFrame(
{'timestamp':[1413840976, 1413842580, 1413760580],
'delta':[1174, 904, 161],
'elapsed':[7673, 9277, 1470]
})
df2 = df.copy()
df['timestamp'] = pd.to_datetime(df['timestamp'], unit='s')
df2.ix[:,2] = pd.to_datetime(df['timestamp'], unit='s')
df
delta elapsed timestamp
0 1174 7673 2014-10-20 21:36:16
1 904 9277 2014-10-20 22:03:00
2 161 1470 2014-10-19 23:16:20
df2
delta elapsed timestamp
0 2014-10-20 21:36:16 1970-01-01 00:00:00.000007673 1970-01-01 00:00:01.413840976
1 2014-10-20 22:03:00 1970-01-01 00:00:00.000009277 1970-01-01 00:00:01.413842580
2 2014-10-19 23:16:20 1970-01-01 00:00:00.000001470 1970-01-01 00:00:01.413760580
```
I strongly suspect the difference in behavior here is problematic and should be resolved. If this is actually "how things should work," I'd greatly appreciate it if someone could explain why the different indexing styles produce these different results

I'll fix this myself, if somebody doesn't get to it quickly. It's good for a first PR, and I've done a couple PRs myself.
Edit: Removed reference to formatters.

A row represents a 'property' and a column represents a record. It's clear and consistent in creation using `dict of Series or dicts` and `dict of ndarrays / lists`. As below
``` py
In [32]: d = {'user1':['Jean', 'Grey', 18, 'F'],
'user2':['Logan', 'Howlett', 33, 'M']}
In [34]: DataFrame(d, index=['firstname','lastname','age','gender'])
Out[34]:
user1 user2
firstname Jean Logan
lastname Grey Howlett
age 18 33
gender F M
```
However when creation using Structed ndarrary, it seems work the other way around, a row represent a record. As below.
``` py
In [45]: dtype=np.dtype([('firstname','U10'),('lastname','U10'),('age','int32'), ('gender', 'U1')])
In [46]: dt = np.array([('Jean','Grey',18,'F'),('Logan', 'Howlett', 33,'M')], dtype=dtype)
In [47]: DataFrame(dt)
Out[47]:
firstname lastname age gender
0 Jean Grey 18 F
1 Logan Howlett 33 M
```
This is bugging me a lot, why is this(I'm guessing the internal store), but is there a way to overcome it?

Considering the following dataframe:
```
In [18]: df = pd.DataFrame(np.random.randn(5,2), index=pd.date_range('2012-01-01', periods=5))
In [19]: df
Out[19]:
0 1
2012-01-01 2.511337 -0.776326
2012-01-02 0.133589 0.441911
2012-01-03 0.348167 1.285188
2012-01-04 1.075843 1.282131
2012-01-05 0.683006 0.558459
```
Slicing with a label that is not included in the index works with `.ix`, but not with `.loc`:
```
In [20]: df.ix['2012-01-03':'2012-01-31']
Out[20]:
0 1
2012-01-03 0.348167 1.285188
2012-01-04 1.075843 1.282131
2012-01-05 0.683006 0.558459
In [21]: df.loc['2012-01-03':'2012-01-31']
...
KeyError: 'stop bound [2012-01-31] is not in the [index]'
```
Context: I was updating some older code, and I wanted to replace `.ix` with `.loc` (as this is what we recommend if it is purely label based to prevent confusion).
Some things:
- If this is intended, I don't find this stated somewhere in the docs. So the docs are at least lacking at this point.
- the inconsistency between `[]`, `.ix[]` and `.loc[]` is a bit surprising here
- it is also inconsistent with `iloc` -> that behaviour was changed in 0.14 to allow out of bound slicing (http://pandas.pydata.org/pandas-docs/stable/whatsnew.html#whatsnew-0140-api)
- Specifically for datetime-line indexing, it is also inconsistent with the feature of partial string indexing: `df.loc['2012-01-03':'2012-01']` will work and do the expected while `df.loc['2012-01-03':'2012-01-31']` fails

```
df = pd.DataFrame({'RandomValues': np.random.randint(1, 50, 60)},
index=pd.date_range("2012-01-01", periods=60))
```
Plotting of course works:
```
In [79]: df.plot()
Out[79]: <matplotlib.axes._subplots.AxesSubplot at 0xf571550>
```
But plotting with matplotlib's `plot` functions gives no longer a datetime formatted x-axis, but just ints:
```
In [80]: plt.plot(df.index, df.RandomValues)
Out[80]: [<matplotlib.lines.Line2D at 0xfb5f748>]
```
**Reason**: matplotlibs `plot` calls `np.atleast_1d` on the input (https://github.com/matplotlib/matplotlib/blob/v1.4.0/lib/matplotlib/axes/_base.py#L220). Previously this returned an Index, now it returns a array of `datetime64` values, which matplotlib can't handle.
Issues:
- This is actually a problem of matplotlib (they should support datetime64), but of course: a lot of users rely now on the behaviour that it did work with a pandas `Index` also.
- Is there a way to restore this behaviour? I don't see directly a solution?
- We should update our docs, as this behaviour is also mentioned there briefly: http://pandas.pydata.org/pandas-docs/stable/visualization.html#plotting-directly-with-matplotlib + figure out why this didn't fail in the doc build (the figure seems not updated with the 0.15 doc build)
It seems there was some discussion about this in the Index-no-subclass PR: https://github.com/pydata/pandas/pull/7891#issuecomment-50936333 and https://github.com/pydata/pandas/pull/7891#discussion_r15862386 (I commented there about exactly this issue, but I don't know why we didn't look further in it then)

Playing with `dateutil` and `pytz` timezones makes me despair of repairing that assertion to be anything sane. Is it actually needed, or can we just turn it into a warning?
Observations:
- two `pytz.DstTzInfo`s of the same zoneinfo zone that have been `.normalize()`ed to different times may compare different
- a `pytz.*TzInfo` has a `zone` member containing the name of the zoneinfo zone from which it was constructed
- a `dateutil.tzfile` has no public members beyond the `tzinfo` API, which is insufficient to tell whether two time zones are equal
- a `pytz` time zone and a `dateutil` time zone appear to compare different under all circumstances, regardless of whether they represent the same time zone
- the various `dateutil` time zone classes have no common base class within the `dateutil` package
- `pytz` zones constructed from different names for the same zoneinfo zone (e.g. `UTC` and `Etc/UTC`) compare different
Ugh.
from #8817
```
import pandas as pd
import pytz
import datetime
dt = datetime.datetime(2014, 11, 14, 0)
dt_est = pytz.timezone('EST').localize(dt)
s = pd.Series(data=[1], index=[dt_est])
s.shift(0, freq='h') # 2014-11-14 00:00:00-05:00 (seems okay)
s.shift(-1, freq='h') # 2014-11-13 18:00:00-05:00 (expected 2014-11-13 23:00:00)

Also refine a bare `except:` in the same method.

Could you please enable pandas on @Sourcegraph by going to https://sourcegraph.com/github.com/pydata/pandas and clicking on Settings? (It should only take 15 seconds.)
Thank you!

I centralized a bit of logic into tile.py's `_bins_to_cuts()` so that this change could be made in one place, hope that's okay.

using relational db to store catagorical columns in seperare tables would be very cool, and rebuilding the frame in pandas by JOIN from the multiple tables would save time on the wire. also memory if categorical was build directly.

something like: `Interval(left=(-1.5,'open),right=(0,'closed'))`
reprs to `(-1.5,0]`
can be used immediately in the index values for `pd.cut` and such (as an object index)
evenutally can form the basis for `IntervalIndex`

Broken (`TypeError: data type not understood`):
``` python
pd.DataFrame(list('abc'),dtype='category')
df=pd.DataFrame(list('abc'), columns=['A'])
df['A'] = df['A'].astype('category')
df.to_records()
```
Works:
``` python
pd.Series(list('abc'), dtype='category')
pd.DataFrame(list('abc'), dtype=pd.core.common.CategoricalDtype)
df=pd.DataFrame(list('abc'), columns=['A'])
df['A'] = df['A'].astype(pd.core.common.CategoricalDtype)
df.to_records()
pd.Series(list('abc'), dtype='category').to_frame().to_records()
```
`to_frame` seems to remove the category dtype though.

That's slow and a `decode` or `decat` method would be trivial:
``` python
df=pd.DataFrame(np.random.choice(list(u'abcde'), 4e6).reshape(1e6, 4),
columns=list(u'ABCD'))
for col in df.columns: df[col] = df[col].astype('category')
%timeit for col in df.columns: df[col].astype('unicode')
1 loops, best of 3: 1.06 s per loop
%timeit for col in df.columns: cats=df[col].cat.categories; cats[df[col].cat.codes]
10 loops, best of 3: 33.2 ms per loop
```
I was working with ~10 categories (partially longer strings) on a 20 mio rows dataset where the difference was even bigger (unfortunately can't reproduce it with dummy data) and using `astype` felt rather buggy (minutes) than only a performance issue.
Given the current limitations on exporting categorical data, having a fast `decode` method would be very convenient. Since category codes are most often strings an optional parameter for direct character set encoding would also be good to have for such a method.
``` python
%timeit for col in df.columns: df[col].astype('unicode').str.encode('latin1')
1 loops, best of 3: 3.95 s per loop
%timeit for col in df.columns: cats=pd.Series(df[col].cat.categories).str.encode('latin1'); cats[df[col].cat.codes]
10 loops, best of 3: 74.5 ms per loop

> In contrast to statistical categorical variables, categorical data might have an order (e.g. ‘strongly agree’ vs ‘agree’ or ‘first observation’ vs. ‘second observation’), but numerical operations (additions, divisions, ...) are not possible.
Similarly to string operations (#8627), arithmetic with scalars could very efficient transform categoricals into new categoricals.
In contrast, array + array operations should probably just return a normal array.

Currently this is only the case for `to_sql` and `to_csv`, where the categories are exported, while `to_pickle` is the only option to persist categorical data
For Stata and HDF it is:
- `to_hdf`: `NotImplementedError: cannot store a category dtype`
- `to_stata`: `ValueError: Data type category not currently understood. Please report an error to the developers.`
As long as a backend does not support categoricals or the conversion is not yet implemented, why not generally export categories as a fallback? With the separately discussed decode method (#8628) this would be easy. If the same rigor (backend supports data type natively or fail) would be applied to CSV-IO we could only export string dtypes to CSV.
Thinking one step further, the `to_...` functions could have an optional parameter named something like `convert_cat` with options:
- None: either try to export as a categorical (pickle, potentially HDF, Stata) or raise exception
- 'category': only export categories (decode method)
- 'code': export s.cat.codes
- 'mapping' or 'emulate': export code:category mapping in one/two columns or separate table/frame/... with the code-category mapping.
The last option would probably need additional parameters to control the technical implementation (e.g. table name for mapping or suffixes as for join/merge, ...)

Wasn't sure whether to post here or on IPython's tracker. The file imports fine, but on the notebook, I get this error when I try to display it:
```

I've tried using encoder options of various kinds when importing the CSV, but nothing seems to work. Running Pandas '0.15.0-20-g2737f5a' on OS X 10.10 and IPython '3.0.0-dev' built from master.
[Here is the spreadsheet in question](http://d.pr/f/12i3G) incase it helps.

I just hacked together some code that supposed to poll a temp/humidity sensor 60 times and then plot the temp against time. Instead of getting a nicely formatted x axis I'm just getting a straight line, and then all the dates from 2010 to 2016 as the x axis. Any ideas? Here's a screencap.

} | 61 | 2014-10-26T21:35:23Z | 2021-04-11T05:23:09Z | null | CONTRIBUTOR | null | *update for 2019-10-07: We have a StringDtype extension dtype. It's memory model is the same as the old implementation, an object-dtype ndarray of strings. The next step is to store & process it natively*.
---
xref #8627
xref #8643, #8350
Since we introduced `Categorical` in 0.15.0, I think we have found 2 main uses.
1) as a 'real' Categorical/Factor type to represent a limited of subset of values that the column can take on
2) as a memory saving representation for object dtypes.
I could see introducting a `dtype='string'` where `String` is a slightly specialized sub-class of `Categroical`, with 2 differences compared to a 'regular' Categorical:
- it allows unions of arbitrary other string types, currently `Categorical` will complain if you do this:
```
In [1]: df = DataFrame({'A' : Series(list('abc'),dtype='category')})
In [2]: df2 = DataFrame({'A' : Series(list('abd'),dtype='category')})
In [3]: pd.concat([df,df2])
ValueError: incompatible levels in categorical block merge
```
Note that this works if they are `Series` (and prob should raise as well, side -issue)
But, if these were both 'string' dtypes, then its a simple matter to combine (efficiently).
- you can restrict the 'sub-dtype' (e.g. the dtype of the categories) to `string/unicode` (iow, don't allow numbers / arbitrary objects), makes the constructor a bit simpler, but more importantly, you now have a 'real' non-object string dtype.
I don't think this would be that complicated to do. The big change here would be to essentially convert any object dtypes that are strings to `dtype='string'` e.g. on reading/conversion/etc. might be a perf issue for some things, but I think the memory savings greatly outweigh.
We would then have a 'real' looking object dtype (and `object` would be relegated to actual python object types, so would be used much less).

As this is inconcistent with how DataFrame concat's work (its a different code-path), so needs updating
```
s = Series(list('abc'),dtype='category')
s2 = Series(list('abd'),dtype='category')
# this should raise
pd.concat([s,s2])
# this should be a category
pd.concat([s,s])
```

https://www.dropbox.com/s/mx3zqot352gdrhq/hg19.txt?dl=0
After reading this into a dataframe, and calling drop_duplicates, the dataframe still has the same number of rows. Though clearly, there are many duplicates contained in the file.
I am using a Mac with 8 gigs of RAM. I'm not sure why this is occurring.

Incorporating this library: https://github.com/libdydn/dynd-python
as an optional dep, allows native Integer NA support (implemented
very similarly to how NaT is represented in `datetime64[ns]` dtypes ATM.
`dynd-python` are the python bindings for `libdynd` and have an almost 100% numpy
compatibility (they use the buffer interface so should be perf-wise pretty costless to do this).

The documentation states that the first parameter (objs) accepts "list or dict of Series, DataFrame, ..." but the routine is rather more forgiving and appears to accept lists, tuples, dicts, and generator objects (very useful!); hence my impression (during usage) was that it accepted "iterables" generally. Unfortunately it turns out this isn't the case; attempting to concatenate a deque of DataFrame objects results in the following:
``` python
from collections import deque
import pandas as pd
df = pd.DataFrame.from_dict({'a': [1, 2, 3], 'b': [4, 5, 6]})
d = deque((df, df, df))
pd.concat(d)
```
```
----> 1 pd.concat(d)
/home/dave/arcticenv/lib/python3.4/site-packages/pandas/tools/merge.py in concat(objs, axis, join, join_axes, ignore_index, keys, levels, names, verify_integrity, copy)
720 keys=keys, levels=levels, names=names,
721 verify_integrity=verify_integrity,
--> 722 copy=copy)
723 return op.get_result()
724
/home/dave/arcticenv/lib/python3.4/site-packages/pandas/tools/merge.py in __init__(self, objs, axis, join, join_axes, keys, levels, names, ignore_index, verify_integrity, copy)
735 raise TypeError('first argument must be a list-like of pandas '
736 'objects, you passed an object of type '
--> 737 '"{0}"'.format(type(objs).__name__))
738
739 if join == 'outer':
TypeError: first argument must be a list-like of pandas objects, you passed an object of type "deque"
```
The error message states that the first argument "must be a list-like of pandas objects" (which is slightly different to the documentation, and closer to the actual implementation's behaviour). Given that a deque is iterable but not indexable (similar to a generator expression) it seems to fulfil the criteria of being "list-like".
Digging into the implementation, the test that's failing appears to be the first line of `_Concatenator.__init__` in `pandas.tools.merge` which reads as follows (in my installation):
``` python
if not isinstance(objs, (list,tuple,types.GeneratorType,dict,TextFileReader)):
raise TypeError('first argument must be a list-like of pandas '
'objects, you passed an object of type '
'"{0}"'.format(type(objs).__name__))
```
So it appears the actual set of iterables accepted by `pandas.concat` is lists, tuples, generator expressions, dicts, and instances of `TextFileReader`. I suggest that it might be better to check for (and act upon) special cases and otherwise assume that `objs` is a suitable iterable of `DataFrame` objects. In other words, get rid of that check entirely, and add a couple of checks for "expected" special cases (such as a user mistakenly passing a `DataFrame` as objs; there's already a check in place for dicts a bit further on).
The conversion of `objs` to a list-comprehension later on (below `if keys is None`) should raise a `TypeError` in the case that it isn't iterable so the change shouldn't cause much impact (i.e. in the case of a non-iterable passed as `objs`, it'll raise an exception of the same class as the existing code).
If this sounds reasonable, I'm happy to provide a pull request?

As a workaround, I'm currently try/except-ing the ValueError and eventually adding a np.nan datapoint at the end of the series (effectively "walking over" the DST change date). At that point I call `resample` which completes correctly and filters away the np.nan datapoint anyway.
Snippet [1] reproduces the bug, calling `resample` on a short series which ends on Oct 26th, which was the DST change date for Europe/Rome. Raised exception is [2]. If relevant, [3] shows the installed versions info.
[1]
``` python
import datetime
import pytz as tz
import pandas as pd
rome = tz.timezone('Europe/Rome')
dr = []
for i in range(2):
dp = datetime.datetime(2014, 10, 25) + datetime.timedelta(days=i)
dr.append(rome.localize(dp))
series = {}
for i, ddr in enumerate(dr):
series[ddr] = i * 10
s1 = pd.Series(series)
s1 = s1.resample('D', how='mean')
```

- this adds a warning that you now have to use `to_pydatetime` as direct plotting with a DatetimeIndex does not work anymore (see #8614)
- I also removed for now the note on speed and explanation of the registered formatters. @agijsberts could you shed some light on this?
- "_The speed up for large data sets only applies to pandas 0.14.0 and later._" Why only for pandas 0.14 or later? And from where does this speed-up come from?
- "_thereby extending date and time support to practically all plot types available in matplotlib_" -> but if you plot directly with matplotlib, I think you don't use the pandas registered formatters? So that sentence seems not fully correct, is that possible? And isn't that the reason for the possible speed-up (matplotlib defaults formatter being faster as pandas' formatter)?

Is this a known issue?
Time offset on 22nd of Sept should be -4 hours in New York as below:
```
pandas.Timestamp('2014-09-22 09:30:00-0400', tz='EST5EDT').tz_convert('EST5EDT')
Timestamp('2014-09-22 09:30:00-0400', tz='EST5EDT')
```
but when providing this twice (-0400 and EST4EDT), the result becomes -0500:
```
pandas.Timestamp('2014-09-22 09:30:00-0400', tz='EST5EDT')
Timestamp('2014-09-22 08:30:00-0500', tz='EST5EDT')
```
Thanks,
Mark

Not sure if this is sensible, but I thought noteworthy.

```
The problem is that when `cat[0]` is the first operand (`type == np.int64`) it orchestrates the execution and the first step is casting it to a rank-0 array (it becomes `array(1)` rather than `np.int64(1)`) and at that point it ceases to pass `np.isscalar` check and corresponding branch of execution is skipped.
The fix is trivial, feel free to beat me to it.
On a broader scale, we might want to review all uses of `np.isscalar` and see if they can also benefit from accepting rank-0 arrays. If that's true, we might want to add `pd.isscalar` function and use it everywhere instead.

Hi all,
I intended to apply a function that gives on each day a ranking based on means calculated from previous n-day's data. The natural way is to use pd.rolling_apply. A toy example:
```
In [93]: df = pd.DataFrame(np.random.randint(10, size=20).reshape(4, 5))
In [94]: df
Out[94]:
0 1 2 3 4
0 2 0 0 2 0
1 9 5 5 6 1
2 2 3 6 8 8
3 5 1 2 9 0
In [95]: import bottleneck as bn
In [96]: bn.nanrankdata(df.mean())
Out[96]: array([ 4. , 1.5, 3. , 5. , 1.5])
```
Up to now, it is cool. Then:
```
In [97]: pd.rolling_apply(df, 2, lambda x: bn.nanrankdata(bn.nanmean(x, axis=0)))
Out[97]:
0 1 2 3 4
0 NaN NaN NaN NaN NaN
1 1 1 1 1 1
2 1 1 1 1 1
3 1 1 1 1 1
```
This is clearly wrong. Is this a bug?

```
skip1<lf>
skip2<lf>
0 1 2<lf>
3 4 5<lf>
```
reading with read_csv() in pandas 0.15.0-42-g20be789 and python 3.4.2 works
```
df = pd.read_csv('test.txt', skiprows=2, delim_whitespace=True, header=None)
df
0 1 2
0 0 1 2
1 3 4 5
```
If I add a space after skip1 so the skipped lines are
```
skip1 <lf>
skip2<lf>
```
then read_csv() throws an error
`CParserError: Error tokenizing data. C error: Expected 1 fields in line 4, saw 3`
Adding 1 to skiprows
`df = pd.read_csv('test.txt', skiprows=3, delim_whitespace=True, header=None)`
does not throw an exception and gives the expected DataFrame
Reading with skiprows=2 and without header=None does not throw an exception and produces a DataFrame with a multiindex
```
skip2
0 1 2
3 4 5
```
If there is a space after skip2 so the skipped lines are
```
skip1<lf>
skip2 <lf>
```
then
`df = pd.read_csv('test.txt', skiprows=2, delim_whitespace=True, header=None)`
does not throw an exception but it does not include the 0 1 2 row in the DataFrame
If there are spaces after skip1 and skip2 so the skipped lines are
```
skip1 <lf>
skip2 <lf>
```
then
`df = pd.read_csv('test.txt', skiprows=2, delim_whitespace=True, header=None)`
throws the CParserError exception but
`df = pd.read_csv('test.txt', skiprows=3, delim_whitespace=True, header=None)`
does not and returns the expected DataFrame
I would expect skiprows to skip the number of lines specified whether or not there are trailing spaces in those lines.

I'm using groupby with apply but the assembled result is incorrect - all rows except row 1 show the same investor B - seems like a bug?
```
In [1]: import pandas as pd
In [2]: import numpy as np
In [3]: df=pd.DataFrame({'InvestorID':[6,6,17,17,19,19,30,40],
...: 'Investor':['AAA','AAA','BBB','BBB','CCC','CCC','EEE','FFF'],
...: 'CurrentPeriodEnd':['7/31/2014','5/31/2014','7/31/2014','5/31/2014','7/31/2014','5/31/2014','7/31/2014','7/31/2014'],
...: 'PriorPeriodEnd':np.nan*8})
In [4]: df
Out[4]:
CurrentPeriodEnd Investor InvestorID PriorPeriodEnd
0 7/31/2014 AAA 6 NaN
1 5/31/2014 AAA 6 NaN
2 7/31/2014 BBB 17 NaN
3 5/31/2014 BBB 17 NaN
4 7/31/2014 CCC 19 NaN
5 5/31/2014 CCC 19 NaN
6 7/31/2014 EEE 30 NaN
7 7/31/2014 FFF 40 NaN
```
this function updates the first positional row in a group with values from the second row
where a group has 2 rows or more
```
In [5]: def f(x):
...: if len(x) >1:
...: x.iloc[0,x.columns.get_loc('PriorPeriodEnd')]=x.iloc[1,x.columns.get_loc('CurrentPeriodEnd')]
...: return x.iloc[0]
In [6]: df.groupby(['InvestorID']).apply(f).reset_index(drop=True)
```
this is not an expected result - the investor column should not have repeating BBB values
```
Out[6]:
CurrentPeriodEnd Investor InvestorID PriorPeriodEnd
0 7/31/2014 AAA 6 5/31/2014
1 7/31/2014 BBB 17 5/31/2014
2 7/31/2014 BBB 19 5/31/2014
3 7/31/2014 BBB 30 5/31/2014
4 7/31/2014 BBB 40 5/31/2014
```
the function below copies the first row first before making updates and it works as expected
```
In [7]: def f(x):
...: top_row=pd.Series(x.iloc[0])
...: if len(x) >1:
...: top_row.iloc[x.columns.get_loc('PriorPeriodEnd')]=x.iloc[1,x.columns.get_loc('CurrentPeriodEnd')]
...: return top_row
```
this is what the result should look like
```
In [8]: df.groupby(['InvestorID']).apply(f).reset_index(drop=True)
Out[8]:
CurrentPeriodEnd Investor InvestorID PriorPeriodEnd
0 7/31/2014 AAA 6 5/31/2014
1 7/31/2014 BBB 17 5/31/2014
2 7/31/2014 CCC 19 5/31/2014
3 7/31/2014 EEE 30 NaN
4 7/31/2014 FFF 40 NaN

Adds a flag which when True returns a DataFrame with columns being the index of the lists generated by the string splitting operation. When False, it returns a 1D numpy array, as before. Defaults to false to not break compatibility.
In the case with no splits, returns a single column DataFrame rather than squashing to a Series.

df.query('a=1')
```
That raises a ValueError. But `df` was modified.
``` python
In [15]: df
Out[15]:
a b
0 1 a
1 1 b
2 1 c
```
versions:
```
pandas: 0.15.0-6-g403f38d
bottleneck: None
tables: None
numexpr: 2.3.1
```
Can't look right now.

The salient difference that makes this segfault occur is if I import pandas before the test run. If I don't, all is well. If I import pandas (and do nothing else differently), the segfault occurs later on (after the pandas import completes without problems), when I call `.apply_async()` on a task in celery, leading kombu to generate a UUID.
This seems to be a matter of the pandas import leaving libuuid1 in some broken state. In particular, it's _not_ a matter of multiple concurrent threads at the time of the segfault; there is only ever one thread, as confirmed by tracing via `threading.settrace` (no output) and by inspecting the core in gdb:

With `sys.settrace` I've narrowed the fault down to this `_uuid_generate_time` call, the last trace events being:

and then the segfault.
This is a CPython 2.7.8 built locally using [pythonz](https://github.com/saghul/pythonz) on Debian Wheezy, and with pandas 0.15.0 installed, inside a virtualenv. Some relevant system package version info:
```
libc-bin 2.13-38+deb7u6
libc-dev-bin 2.13-38+deb7u6
libc6:i386 2.13-38+deb7u6
libc6-dev:i386 2.13-38+deb7u6
libc6-i686:i386 2.13-38+deb7u6
libuuid1:i386 2.20.1-5.3
```
Anything else I can provide that's useful?

Enhances `pd.concat` to work with any iterable (except specifically undesired ones like pandas objects and strings). A new test is included covering tuples, lists, generator expressions, deques, and custom sequences, and all existing tests still pass. Finally, a "what's new" entry is included (not sure this last is correct - but [pull requests guidelines](https://github.com/pydata/pandas/blob/master/CONTRIBUTING.md) mentioned it)

If values in B are larger than values in A - replace those values with values of A. I used to do this by doing df.B[df.B > df.A] = df.A, however recent upgrade of pandas started giving a SettingWithCopyWarning when encountering this chained assignment. Official documentation recommends using .loc.
Okay, I said, and did it through df.loc[df.B > df.A, 'B'] = df.A and it all works fine, unless column B has all values of NaN. Then something weird happens:
``` python
In [1]: df = pd.DataFrame({'A': [1, 2, 3],'B': [np.NaN, np.NaN, np.NaN]})
In [2]: df
Out[2]:
A B
0 1 NaN
1 2 NaN
2 3 NaN
In [3]: df.loc[df.B > df.A, 'B'] = df.A
In [4]: df
Out[4]:
A B
0 1 -9223372036854775808
1 2 -9223372036854775808
2 3 -9223372036854775808
```
Now, if even one of B's elements satisfies the condition (larger than A), then it all works fine:
``` python
In [1]: df = pd.DataFrame({'A': [1, 2, 3],'B': [np.NaN, 4, np.NaN]})
In [2]: df
Out[2]:
A B
0 1 NaN
1 2 4
2 3 NaN
In [3]: df.loc[df.B > df.A, 'B'] = df.A
In [4]: df
Out[4]:
A B
0 1 NaN
1 2 2
2 3 NaN
```
But if none of B's elements satisfy, then all NaNs get replaces with -9223372036854775808:
``` python
In [1]: df = pd.DataFrame({'A':[1,2,3],'B':[np.NaN,1,np.NaN]})
In [2]: df
Out[2]:
A B
0 1 NaN
1 2 1
2 3 NaN
In [3]: df.loc[df.B > df.A, 'B'] = df.A
In [4]: df
Out[4]:
A B
0 1 -9223372036854775808
1 2 1
2 3 -9223372036854775808
```
Am I doing something wrong, or this is a bug?

``` python
import pandas as pd
import numpy as np
df = pd.DataFrame({'A': [1, 2, 3],'B': [np.NaN, np.NaN, np.NaN]})
df
Out[6]:
A B
0 1 NaN
1 2 NaN
2 3 NaN
df.dtypes
Out[10]:
A int64
B float64
dtype: object
# This loc shouldn't match any rows
df.loc[df.B > df.A, 'B'] = df.A
df
Out[8]:
A B
0 1 -9223372036854775808
1 2 -9223372036854775808
2 3 -9223372036854775808
# Why has this become int? Is this expected
# behaviour for this assignment
df.dtypes
Out[12]:
A int64
B int64
dtype: object
```
As long as some of the rows in the `.loc` match, this seems to work okay:
``` python
df = pd.DataFrame({'A': [1, 2, 3],'B': [np.NaN, 4, np.NaN]})
df.loc[df.B > df.A, 'B'] = df.A
df
Out[4]:
A B
0 1 NaN
1 2 2
2 3 NaN
```
I don't know why the `B` column gets converted to int64. Is the weird value in the B column the result of the `np.nan` bit pattern being inserted into an `int64` series?
My `pd.show_versions()`:
```

I want to truncate (or even drop) an existing table in SQL server. I didn't find any dedicated function in pandas.io.sql. So I tried to create an empty data frame just to call:
```
df1 = pd.DataFrame()
df1.to_sql(out_tbl, engine, if_exists='replace', index=False)
```
This code does drop the table but then generates exception from sqlalchemy as it tries to re-create an empty table. I can catch and ignore it, and the next call to_sql() with if_exists='append' will create the table correctly, but this is pretty ugly.
Another way I tried is to clear all the rows from the original data frame, leaving the columns:
```
df1 = df.drop(df.index)
df1.to_sql(out_tbl, engine, if_exists='replace', index=False)
```
This almost works: it truncates the table but then insert a single record with all fields as NULL...
You can see the full description at http://stackoverflow.com/questions/26205057/how-can-i-truncate-a-table-using-pandas#comment41130846_26205057

In the case where the array is `ints` but the series is `floats` this can have odd results in Python 2.x with division. This was surprising to me because, element-wise, a float/int computation would upcast the denominator to a float. But not here in this vectorized case:
```
import numpy as np
import pandas as pd
j = np.array([0] * 5)
k = np.random.randn(5)
print j / k
print (j / pd.Series(k)).values
print (pd.Series(j) / k).values
print (pd.Series(j) / pd.Series(k)).values
####output####
[-0. 0. -0. -0. 0.]
[ inf inf inf inf inf]
[-0. 0. -0. -0. 0.]
[-0. 0. -0. -0. 0.]
```
So in the two "pure" cases (array and array, series and series) the ints are upcast to floats and we get 0's everywhere. In the 2nd mixed case (3rd case overall), everything gets converted to floats to match the array and everything goes fine. But in the 1st mixed case (2nd case overall) everything gets converted to ints to match the array and so you get what was, at least to me, an unexpected infinite result.

If I use the default C engine with `read_table` I have to specify `skiprows=85` to properly load the table:
``` python
pd.read_table(
'co2_mm_mlo.txt.', sep=r'\s+', header=None, skiprows=85, engine='c',
names=['year', 'month', 'dec_year', 'average', 'interpolated', 'trend', 'days'])
```
But if I use the Python engine then the expected `skiprows=72` works:
``` python
pd.read_table(
'co2_mm_mlo.txt.', sep=r'\s+', header=None, skiprows=72, engine='python',
names=['year', 'month', 'dec_year', 'average', 'interpolated', 'trend', 'days'])
```
The resulting DataFrame is expected to have 679 rows, but has 691 rows and data from the header if I use `skiprows=72` with the C engine.
I've confirmed this behavior on Mac OS X Yosemite with Pandas 0.15.0 and a checkout of master@5cf3d85a7d4c448519fa08f918a114209cfbdf2b.

The first commit adds `Index.is_monotonic_decreasing` and `Index.is_monotonic_increasing` (alias for `is_monotonic`).
`is_monotonic` will have a performance degradation (still O(n) time) in cases where the Index is decreasing monotonic. If necessary, we could work around this, but I think we can probably get away with this because the fall-back options are much slower and in many cases (e.g., for slice indexing) the next thing we'll want to know is if it's decreasing monotonic, anyways.
Next up will be handling indexing monotonic decreasing indexes with reversed slices, e.g., `s.loc[30:10]`.

I think it's good for .loc to have accept booleans, but it's misleading and confusing for the docs to say (in bold, no less) that it accepts _only_ labels found in the index, and then immediately contradict themselves by saying it also accepts arrays of booleans. Booleans aren't labels found in the index.

But what happens if I start off with the following in a session
<pre><code>df = pd.DataFrame(np.arange(10))
store1 = pd.HDFStore('test.h5')
store2 = pd.HDFStore('test.h5')
some_unmemorable_name = pd.HDFStore('test.h5')
</code></pre>
and I do some stuff with these stores, such as
<pre><code>store1.append('df1', df)
store2.append('df2', df)
store1.close()
store2.close()
</code></pre>
then, I spend some time doing a bunch of stuff unrelated to the stores, after which I want to save stuff to 'test.h5' again but to overwrite if it's already there. At this point, I have already forgotten about not having closed <code>some_unmemorable_name</code>. If I open the file with <code>mode = 'w'</code> now,
<pre><code>In [63]: store = pd.HDFStore('test.h5', mode = 'w')
/nuwa_cluster/opt/anaconda3-2.0.1/lib/python3.4/site-packages/tables/file.py in open_file(filename, mode, title, root_uep, filters, **kwargs)
313 raise ValueError(
314 "The file '%s' is already opened. Please "
--> 315 "close it before reopening in write mode." % filename)
316
317 # Finally, create the File instance, and return it
ValueError: The file 'test.h5' is already opened. Please close it before reopening in write mode.
</pre></code>
and there is no way to close the opened store because it was opened so long ago that I cannot recall its name. Deleting the file doesn't help because the current session is still 'aware' of the opened store. Restarting the session means that everything will have to be done again. If there is way to be able to get the names of all currently opened stores, then they can all be closed.

Here's what I've got so far:
``` python
>>> import pandas as pd
>>> from sqlalchemy import create_engine
>>> import psycopg2
>>> basedata = pd.read_excel('mydata.xlsx')
>>> engine = create_engine('postgresql://myusername@localhost:5432/mydb')
>>> pd.io.sql.get_schema(basedata, 'basedata', con=engine)
```
Unfortunately the CREATE TABLE statement generated uses a column type of "DATETIME" that does not exist in PostgreSQL. I suspect that the engine object is being ignored somehow and the DDL I'm getting is for sqlite, not PostgreSQL. However, I can't get pandas to build on my Mac so that I can expand the tests to validate my assumption.

Though I its pretty straightforward to add support for this directly to a Timedelta, after the notion is the same, _though_ a `time` object can support a time-zone so not sure if this is odd (or maybe we should add an optional tz to Timedelta).
```
In [5]: from datetime import time
In [6]: time(secIn [8]: pd.Timedelta(time(second=1))
ValueError: Value must be Timedelta, string, integer, float, timedelta or convertible
In [9]: pd.Timedelta('1s')
Out[9]: Timedelta('0 days 00:00:01')
```

```
In [2]: df = DataFrame(1,columns=range(10),index=range(10))
In [3]: df.iloc[1,1] = np.nan
```
Default for a small frame (currently) is to show the non-null counts
```
In [5]: df.info()
<class 'pandas.core.frame.DataFrame'>
Int64Index: 10 entries, 0 to 9
Data columns (total 10 columns):
0 10 non-null float64
1 9 non-null float64
2 10 non-null float64
3 10 non-null float64
4 10 non-null float64
5 10 non-null float64
6 10 non-null float64
7 10 non-null float64
8 10 non-null float64
9 10 non-null float64
dtypes: float64(10)
memory usage: 880.0 bytes
# allow it to be turned off
In [6]: df.info(null_counts=False)
<class 'pandas.core.frame.DataFrame'>
Int64Index: 10 entries, 0 to 9
Data columns (total 10 columns):
0 float64
1 float64
2 float64
3 float64
4 float64
5 float64
6 float64
7 float64
8 float64
9 float64
dtypes: float64(10)
memory usage: 880.0 bytes
```
When you have a big frame, right now you need to set max_info_rows to control this option
```
In [7]: pd.set_option('max_info_rows',5)
In [8]: df.info()
<class 'pandas.core.frame.DataFrame'>
Int64Index: 10 entries, 0 to 9
Data columns (total 10 columns):
0 float64
1 float64
2 float64
3 float64
4 float64
5 float64
6 float64
7 float64
8 float64
9 float64
dtypes: float64(10)
memory usage: 880.0 bytes
# force it to show
In [9]: df.info(null_counts=True)
<class 'pandas.core.frame.DataFrame'>
Int64Index: 10 entries, 0 to 9
Data columns (total 10 columns):
0 10 non-null float64
1 9 non-null float64
2 10 non-null float64
3 10 non-null float64
4 10 non-null float64
5 10 non-null float64
6 10 non-null float64
7 10 non-null float64
