Python isinstance () returns an error with datetime.date

Question

I am trying to compile the old code of 2008 .

import datetime

if isinstance(value, datetime.date):

But I have an error:

isinstance () arg 2 must be a class, type or tuple of classes and types Python executable: /usr/bin/python2.6 Python Version: 2.6.5

What am I missing?

Answer 1

I suspect that you imported the wrong date-time, as in:

from datetime import datetime

use instead:

import datetime

Answer 2

I run Python 2.7 and sometimes also came across this error. Often a simple type check will suffice unless you need a strict instance check.

if id(type) and type(value) in (datetime.datetime, datetime.date):
