How many types of inheritance are there in 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
