How do I tell if a column in a pandas dataframe is of type datetime? How do I tell if a column is numerical?

Question

I am trying to filter the columns in a pandas dataframe based on whether they are of type date or not. I can figure out which ones are, but then would have to parse that ou

Answer 1

bit uglier Numpy alternative:

In [102]: df.loc[:, [np.issubdtype(t, np.datetime64) for t in df.dtypes]]
Out[102]:
    date_col
0 2017-02-01
1 2017-03-01
2 2017-04-01
3 2017-05-01

In [103]: df.loc[:, [np.issubdtype(t, np.number) for t in df.dtypes]]
Out[103]:
   col1  col2
0     1     2
1     1     2
2     1     2
3     1     2
