Overriding and Overloading

Method Overloading: Method Overloading is an example of Compile time polymorphism. In this, more than one method of the same class shares the same method name having different signatures. Method overloading is used to add more to the behavior of methods and there is no need of more than one class for method overloading.
Note: Python does not support method overloading. We may overload the methods but can only use the latest defined method.

Method Overriding: Method overriding is an example of run time polymorphism. In this, the specific implementation of the method that is already provided by the parent class is provided by the child class. It is used to change the behavior of existing methods and there is a need for at least two classes for method overriding. In method overriding, inheritance always required as it is done between parent class(superclass) and child class(child class) methods.

Python Operator Overloading

You can change the meaning of an operator in Python depending upon the operands used. In this tutorial, you will learn how to use operator overloading in Python Object Oriented Programming. Python operators work for built-in classes. But the same operator behaves differently with different types. For example, the + operator will perform arithmetic addition on two numbers, merge two lists, or concatenate two strings.

This feature in Python that allows the same operator to have different meaning according to the context is called operator overloading.
