It seems that when Python documentation says delegates method calls to a parent or sibling class it means to a parent or parent's sibling which is also a base class of a. It is the definition of the Python documentation that threw me off the course. It is a class that inherits from the same parent. And the MethodA() of ClassB in its turn will just print and exit since it doesn't use super() function to delegate the method call further up the MRO chain. A sibling class is what I was thinking it was. It describes the possible states and behaviors that every object of a.
#SUPER IN OOP PYTHON CODE#
A class is a code template for creating objects, we can think of it as a blueprint. The basic building blocks of OOP are objects and classes. Now if you follow the MRO the super() function of MethodA() of ClassC will call the MethodA() of ClassA, which before printing will call MethodA() of classB (since it's next in MRO). Object-oriented programming is a method of organizing a program by grouping related properties and behaviors into individual objects. The MRO of the ClassC as printed with print(ClassC._mro_) is If you as me wonder why MethodA of Class0 never gets printed, here is the explanation as I understand it. In object-oriented terminology when class X extend class Y, then Y is called super class or base class and X is called subclass or derived class. Here's an interesting case I found while experimenting with super() function: class Class0(object): Super() function delegates a method call to a parent's sibling class automatically based on MRO (method resolution order). That is a diamond inheritance must take place. It seems that when Python documentation says delegates method calls to a parent or sibling class it means to a parent or parent's sibling which is also a base class of a given child. It is a class that inherits from the same parent. The super in Python returns a temporary proxy object of the immediate parent class that can be used to call methods of the parent class. Inheritance is when a new class uses code from another class. One core feature of object-oriented programming languages like Python is inheritance. This helps reduce repetition in your code. After some further research and reading Python’s super() considered super! article I came to the following conclusions:Ī sibling class is what I was thinking it was. The Python super () method lets you access methods from a parent class from within a child class. Constructor in Object Oriented Programming (OOPs) in Python Python Programming Constructor: Constructor are just a special type of method.
