Object Oriented Programming

In programming, polymorphism refers to methods/functions/operators with the same name that can be executed on many objects or classes. "Polymorphism" means many forms.

An example of polymorphism is len(). len() can be used with multiple data types like string, list, tuple, dictionary.

Polymorphism is used in Class methods, where we can have multiple classes with the same method name.

Example

Let there be three classes class1, class2, class3.

number method is an example of polymorphism.

third!

Polymorphism works in inheritance too. When the parent class has a method and child class has a method of the same name.
