How to check whether a variable is a class or not?

Question

I was wondering how to check whether a variable is a class (not an instance!) or not.

I\'ve tried to use the function isinstance(object, class_or_type_or_tuple

Answer 1

class Foo: is called old style class and class X(object): is called new style class.

Check this What is the difference between old style and new style classes in Python? . New style is recommended. Read about "unifying types and classes"
