How does issubclass() function work in Python?

We can derive a class from multiple parent classes as follows −

class A:        # define your class A .....
class B:         # define your class B .....
class C(A, B):   # subclass of A and B .....

We can use issubclass() function to check the relationships of two classes and instances.

• For example, the

issubclass(sub, sup)

•  boolean function returns true if the given subclass sub is indeed a subclass of the superclass sup.
