Inheritance is a core concept in Object Oriented programming. It allows the programmer to create a hierarchy of classes that share a set of properties and methods.

This is done by deriving a class from another. So one class can inherit the properties of another class. Derived class from Base class.

Example

In order to inherit Derived class (Student) from Base class (MakeLabs), we have to put base class name inside parenthesis.

Example

Output

My name is Tyson, Mike Tyson

__init__() function when added to the derived class won't inherit from parent class' __init__ function.

Example

Student class no longer has attributes like name and last_name.

super() Function is used to inherit all the methods and properties from its parent class.

Example 1

Output

<__main__.MakeLabs object at 0x0000019883245F10>

Functions that belong to the objects are called methods. Let's create a function in MakeLabs class.

Example

Output

My name is Bond, James Bond

The self parameter references to the current instance of the class. The self parameter is used to access variables that belong to the class.

The name self is a convention to be followed.

Example

When we call p1.my_function() python automatically takes it as MakeLabs.my_function(). This is what self is for.
