[Tutor] isinstance versus 'is'?

Hi all,
Thanks for all the help regarding decorators. It makes more sense now.

I was double checking that I remembered the isinstance order of arguments
correctly by using the command line interpreter, and found something very

>>> a = 5
>>> isinstance(a, int)
>>> a is int

What happened there? Don't these do the same thing? I thought I could use
them interchangeably?
