How to check class equality in Python 2.5?

问题

I've looked through Python 2.5 documentation and I couldn't find an answer to this: How do I check if an object is the same class as another object?

def IsClass(obj1, obj2):
     return obj1.class == obj2.class #doesn't work

回答1:

You can use

type(obj1) is type(obj2)

Note that you usually try to avoid type checking in Python, but rather rely on duck typing.

回答2:

I think what you want to do is use type(obj). :)

-EDIT- Looks like he beat me to it. And he's right about the Duck Typing.
