Nit: In the documentation of DataFrame.any, the 'axis' argument is missing
The [current online documentation of `pandas.DataFrame.any`](http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.any.html) omits the `axis` keyword, as e.g. [described for concat](http://pandas.pydata.org/pandas-docs/stable/generated/pandas.concat.html).

However, the following works:
```python
pd.DataFrame([[True, False]]).any(axis=1)
```
