How can tell if an object is a subclass of something else?
Imagine...
class Thing:
pass
class Animal:
pass
class Dog:
pass
d = Dog()
I want to find out that 'd' is a Dog, Animal and Thing. Such as...
d is a Dog
d is a Animal
d is a Thing
Thanks

First you need to subclass the classes so that Dog actually is a
subclass of Animal which is a subclass of thing...
class Thing:
pass
class Animal(Thing):
pass
class Dog(Animal):
pass
class Weapon(Thing):
pass
class Gun(Weapon):
pass
Then you can use 'isinstance'
d = Dog()
yea i meant to have animal extend thing and dog extend animalmy
mistake.
anyways, is there a way to check without having an instance of the
class?
such as,
isinstance(Dog, (Animal, Thing)) ??
thanks

issubclass(Dog, Animal)
Note that such tests should only be used in a

In [1]: class A:
...: pass
...:
In [2]: class B(A):
...: pass
...:
In [3]: issubclass(B, A)
Out[3]: True
In [4]: isinstance(B(), B)
