Now we'll see how to perform inheritance when a class has a constructor function. Until now, we saw a simple demonstration of the class inheritance in which a subclass gains the methods and attributes of the superclass by just passing it as an argument. We created the instance for the subclass Number and then accessed the sum function from the superclass or parent class Calculate. The subclass Number inherited the superclass Calculate and now the methods inside it can now be accessed by the subclass Number.
CLASS INHERITANCE PYTHON CODE
The above code is no different from the code that we discussed earlier where we saw the first glimpse of class inheritance in Python. # Subclass or Derived Class class Number( Calculate): pass # Parent or Base Class class Calculate: def sum( self, a, b): Here is an example of single inheritance. In simple words, the derived class or subclass has only one direct parent class. Single inheritance can be defined as an inheritance where a subclass or derived class inherits from a single superclass or parent class.
CLASS INHERITANCE PYTHON UPDATE
Inheritance helps us reduce the effort that we put into writing the same logic again and again and makes it easy to maintain and update the code. Genius Millionaire Playboy Philanthropist We accessed the method power using the class Ironman which inherited the method power from the class Hero. The subclass Ironman now has access to all the attributes and methods of the superclass Hero as well. Then we created a subclass Ironman that inherits the superclass Hero and the subclass Ironman has its own method speciality that specifies the specialities of Ironman. The class Hero has a method power that returns a specific power a hero has. Print( "Genius", "Millionaire", "Playboy", "Philanthropist") This allows us to reuse the code as well as we can extend or modify the behaviour of the superclass.įor example- class Hero: def power( self):Ĭlass Ironman( Hero): def speciality( self): The classes that inherit the methods and attributes from the parent class are called subclass and the existing class is called a superclass.Īs soon as a subclass inherits the superclass, it gains all of the methods and attributes of the superclass. Inheritance can be defined as the mechanism that permits the newly created classes to inherit the methods and attributes of the existing class or parent class.
Object-Oriented Programming has four important concepts and one of them is inheritance. It provides a way to structure and organize the code in such a manner that makes it easier to maintain and scale the code.Ĭlasses are an essential concept in OOP or we can say that classes are the building blocks of Object-Oriented Programming which is a programming model based on objects and classes. OOP is an integral part of any programming language that helps carry out complex concepts. We all have ever encountered the term OOPs (Object-Oriented Programming) in programming.
