Code Sample, a copy-pastable example if possible

code sample from DataFrame.select_dtypes docstring

>>> import pandas as pd
>>>
>>> pd.__version__
'0.26.0.dev0+767.gb3490cbd9'
>>>
>>> df = pd.DataFrame({"a": [1, 2] * 3, "b": [True, False] * 3, "c": [1.0, 2.0] * 3})
>>> df
   a      b    c
0  1   True  1.0
1  2  False  2.0
2  1   True  1.0
3  2  False  2.0
4  1   True  1.0
5  2  False  2.0

Problem description

seen locally on master and 0.25.1

The docstring implies "int" is a valid dtype to exclude. Only "int64" produces the expected output shown in the docstring.

The same applies to the include argument.

Expected Output

>>> df.select_dtypes(exclude=["int64"])
       b    c
0   True  1.0
1  False  2.0
2   True  1.0
3  False  2.0
4   True  1.0
5  False  2.0
>>>

Thanks @pambot. as well as 'int64', the string 'integer' also works. The code sample is the last example in the docstring. https://dev.pandas.io/docs/reference/api/pandas.DataFrame.select_dtypes.html
