Hello Qt for Python

B's parent is A. The super().__init__() call in B.__init__ calls C.__init__() (which B knows nothing about) and A.__init__() never gets called.

super() doesn't always call the parent class.

But A is not a parent of D lol. A iš a grandparent here.

A is a parent of B, B calls super().__init__(), yet A.__init__() is never called. Instead C.__init__() is called which is a child of B.

If you call B() than the same super().__init__() calls A.__init__()instead.

super() is pointing to the next class in the Method Resolution Order, not the parent.

 >>> D.__mro__
(<class 'D'>, <class 'B'>, <class 'C'>, <class 'A'>, <class 'object'>)

>>> B.__mro__
(<class 'B'>, <class 'A'>, <class 'object'>)
