Python Inheritance

Python Inheritance:

The support is a basic characteristic of an oriented program. Python inheritance-It is a process for creating a new class, called a classroom, a classroom, called class base. The support is a very expensive way to recycle and exchange information and features that are already defined in Elementary class, including being able to include new information and derivative class structures. Because the derivative level inherits all Class Characteristics, grade level has many parts of the suburbs below Level.

However, classified classes may change some or all parts of the classroom.
Each of the sections below is inherited by the state (which is different types) from the super class level. Bicycles and tandem are shared with some governments: clear, fast and fast. In addition, each of the sub-sections is inherited in high-quality systems.

Introduction:

The lower grades are not limited to the state and the super class nature. The following methods can add variables and methods in the literature. Bicycles Tandem have two councilors and two Wheel barbers; Some mountain bikes have an extra large ring, giving them a lower sum.

Classes can inherit other classes. The class may inherit the characteristics and characteristics of the classroom in another class, known as the super class. The class of super class is called subclass, also called the inheritance class or the classroom. Mirror glass is also known as ancestry. There is a connection between the classes. It’s like relationships or categorizations to find out about real life. Think about cars, for example. Bicycles, cars, buses and cars are a car. Cars, cars, cars, cars and cars are all vehicles and cars are a car. We can do the Python car class, with a lot of cheap and easy ways. Cars, buses and cars and bicycles can be applied to a lower level that will inherit the car systems.

Python Inheritance Syntax:

To make another classroom class, we can apply the name of the lower class for the class to define the common class.

Syntax:

>>> class Person:

                pass

>>> class Student(Person):

                pass

>>> issubclass(Student,Person)

Python Inheritance Example:

Let’s see a simple python inheritance example where we are using two classes: Animal and Dog. Animal is the parent or base class and Dog is the child class.

Here, we are defining eat() method in Animal class and bark() method in Dog class. In this example, we are creating instance of Dog class and calling eat() and bark() methods by the instance of child class only. Since, parent properties and behaviors are inherited to child object automatically, we can call parent and child class methods by the child instance only.

Example:

class Animal:   

def eat(self):  

print 'Eating...'  

class Dog(Animal):     

def bark(self):  

print 'Barking...'  

d=Dog()  

d.eat()  

d.bark()

Output:

Eating...  

Barking...

Multiple Inheritance

Multiple Python inheritance are when multiple python classes inherit from a class.

Example: 

class First(object):  

  def __init__(self):  

    super(First, self).__init__()  

    print("first")  

class Second(object):  

  def __init__(self):  

    super(Second, self).__init__()  

    print("second")  

class Third(Second, First):  

  def __init__(self):  

    super(Third, self).__init__()  

    print("third")    

Third();

 

Output:

first  

second  

third

Multilevel Inheritance

When one class inherited from another, which is between the other, it is the inheritance of many Python inheritance.

Example: 

class Animal:   

    def eat(self):  

      print 'Eating...'  

class Dog(Animal):  

   def bark(self):  

      print 'Barking...'  

class BabyDog(Dog):  

    def weep(self):  

        print 'Weeping...'  

d=BabyDog()  

d.eat()  

d.bark()  

d.weep()

Output:

Eating...  

Barking...

Weeping
