Python: how can I check whether an object is of type datetime.date?

Question

I have tried a few obvious options but none of them works:

In [150]: x
Out[150]: datetime.date(2012, 9, 1)

In [151]: type(x)
Out[151]: datetime.date

In [15         


        

Answer 1

i believe the reason it is not working in your example is that you have imported datetime like so :

from datetime import datetime

this leads to the error you see

In [30]: isinstance(x, datetime.date)
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/<ipython-input-30-9a298ea6fce5> in <module>()
----> 1 isinstance(x, datetime.date)

TypeError: isinstance() arg 2 must be a class, type, or tuple of classes and types

if you simply import like so :

import datetime

the code will run as shown in all of the other answers

In [31]: import datetime

In [32]: isinstance(x, datetime.date)
Out[32]: True

In [33]:
