How many types of inheritance are there in Python?

Object Oriented Programming Programming Python

Inheritance is concept where one class accesses the methods and properties of another class.

Parent class is the class being inherited from, also called base class.
Child class is the class that inherits from another class, also called derived class.

There are two types of inheritance in python −

Multiple Inheritance
Multilevel Inheritance

Multiple Inheritance −

In multiple inheritance one child class can inherit multiple parent classes.

Example

class Father:
   fathername = ""
   def father(self):
      print(self.fathername)

class Mother:
   mothername = ""
   def mother(self):
      print(self.mothername)

class Daughter(Father, Mother):
   def parent(self):
      print("Father :", self.fathername)
      print("Mother :", self.mothername)

s1 = Daughter()
s1.fathername = "Srinivas"
s1.mothername = "Anjali"
s1.parent()

Output

Father : Srinivas
Mother : Anjali

Multilevel Inheritance

In this type of inheritance, a class can inherit from a child class/derived class.

Example

#Daughter class inherited from Father and Mother classes which derived from Family class.
class Family:
   def family(self):
      print("This is My family:")

class Father(Family):
   fathername = ""
   def father(self):
      print(self.fathername)

class Mother(Family):
   mothername = ""
   def mother(self):
      print(self.mothername)
   
class Daughter(Father, Mother):
   def parent(self):
      print("Father :", self.fathername)
      print("Mother :", self.mothername)

s1 = Daughter()
s1.fathername = "Srinivas"
s1.mothername = "Anjali"
s1.family()
s1.parent()

Output

This is My family:
Father : Srinivas
Mother : Anjali

Sri
