How do I check (at runtime) if one class is a subclass of another?

Question

Let\'s say that I have a class Suit and four subclasses of suit: Heart, Spade, Diamond, Club.

class Suit:
   ...
class Heart(Suit):
   ...
class Spade(Suit):         


        

Answer 1

You can use issubclass() like this assert issubclass(suit, Suit).
