Can you explain what is metaclass and inheritance in Python?
Every class is an object. It's an instance of something called a metaclass. The default metaclass is typed. You can check this using the is instance function. For example,
class Foo: pass foo = Foo() isinstance(foo, Foo) isinstance(Foo, type)
This will give the output:
True True
A metaclass is not part of an object's class hierarchy whereas base classes are. These classes are used to initialize the class and not its objects.
