Getting error while trying to read csv using pandas Python due to extra column values
Here is the scenario that I am trying to rid of:
I am trying to read the following type of csv:

```
para1,para2,para3,para4
1,2,3,4
1,2,3,4,5
1,2,3,4
2,3,4,5,6,7,8,9,0
```
I am using the following command and getting the following error:

```
>>> import pandas as pd
>>> df =pd.read_csv("test.csv")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python35\lib\site-packages\pandas\io\parsers.py", line 702, in parser_f

pandas.errors.ParserError: Error tokenizing data. C error: Expected 4 fields in line 3, saw 5
```
I tried to search for the issue and got this thread on SO:
Python Pandas Error tokenizing data

So, I tried. This is not what I was expecting. It is truncating the values.

```
>>> df =pd.read_csv("test.csv",error_bad_lines=False)
b'Skipping line 3: expected 4 fields, saw 5\nSkipping line 5: expected 4 fields, saw 9\n'
>>> df
para1  para2  para3  para4
0      1      2      3      4
1      1      2      3      4
```
What I wanted is something like this:
if there are extra values, then take the columns as the integer values with the highest column found in extra. then make the rest of the values as zero(0) till the last column and read the csv.

The output I am expecting is something like this:

```
>>> df =pd.read_csv("test.csv")
>>> df
   para1  para2  para3  para4    0    1    2    3    4
0      1      2      3      4  NaN  NaN  NaN  NaN  NaN
1      1      2      3      4  5.0  NaN  NaN  NaN  NaN
2      1      2      3      4  NaN  NaN  NaN  NaN  NaN
3      2      3      4      5  6.0  7.0  8.0  9.0  0.0
>>> df = df.fillna(0)
>>> df
   para1  para2  para3  para4    0    1    2    3    4
0      1      2      3      4  0.0  0.0  0.0  0.0  0.0
1      1      2      3      4  5.0  0.0  0.0  0.0  0.0
2      1      2      3      4  0.0  0.0  0.0  0.0  0.0
3      2      3      4      5  6.0  7.0  8.0  9.0  0.0
```
But please take a note of, I do not want to take care of the column. Instead the program must automatically understand and make the column headers as given above.

Second, please try to avoid suggesting me to write the header. As there can be number of columns where I might not able to write the header but just leave it as it is. so the missing column header will be the number integer as stated above. Do someone have any solution for the query, please let me know?
