How to compare type of an object in Python?

Question

Basically I want to do this:

obj = 'str'
type ( obj ) == string

I tried:

type ( obj ) == type ( string )

and it didn't work.

Also, what about the other types? For example, I couldn't replicate NoneType.

Answer 1

isinstance()

In your case, isinstance("this is a string", str) will return True.
