Inheritance is a way by which a subclass can inherit the attributes and methods of another class. The new class is called derived (or child) class and the one from which it inherits is called the base (or parent) class.
There are three types of inheritance in Python:
In single inheritance, the derived class is derived from only one base class.
The general syntax for single class inheritance is:
class BaseClass: Base class body class DerivedClass(BaseClass): Derived class body
In multiple inheritance, the derived class is derived from more than one base class.
The general syntax for multiple class inheritance is:
class BaseClass1: Base class1 body class BaseClass: Base class2 body class DerivedClass(BaseClass1,BaseClass2): Derived class body
In multilevel inheritance, the derived class is derived from another derived class.
The general syntax for multilevel class inheritance is:
class Base: Base Class body class Derived1(Base): Derived Class1 body class Derived2(Derived1): Derived Class2 body
Here are a few main advantages of using Inheritance:
Since the derived class inherits features from the base class, adding new features to it. This results in re-usability of code. This makes the code more scalable.
By dividing the code into classes, we can structure our software better by dividing functionality into classes.
