How to check subclass in python

An object oriented in python is different from full-support object oriented like java or etc. To check subclass, we need to use built-in function from python called "issubclass"

Ok, let's begin with issubclass(class, classinfo).

class A(object):
 pass

class B(A):
 pass

a = A()
b = B()

print issubclass(a.__class__,A)
print issubclass(b.__class__,B) 

It is easy right? ^^
