Inheritance-Object Oriented Programming (OOPs) concept in python
Inheritance
Inheritance is the most important aspect of object-oriented programming. It provides the re-usability of the code.
Parent class :It is base class ,child class :another class and also called child class
Types of Inheritance:
Single inheritance
Multilevel inheritance
Multiple inheritance
Hierarchical inheritance
Hybrid inheritance
The Single Inheritance
Single Inheritance is the most important aspect of object-oriented programming.
Single Inheritance have single parant and single class.
Single Inheritance have single parant and single class.

| Single Inheritance |
Example:
class Employee: --------------------------------------------------(parent class)
def emp_id(self,id):
print("employee id is",id)
def emp_name(self,name):
print("employee name is",name)
class company(Employee):--------------------------------------(child class)
def com_id(self,id):
print("company id is",id)
def com_name(self,name):
print("company name is",name)
c=company()
c.emp_id(9999)
c.emp_name("antrow")
c.com_id(1)
c.com_name("google")
Multilevel inheritance
Multilevel inheritance have single parent class and multi child class.

| Multilevel Inheritance |
Example:
class Employee:------------------------------------------(Parent class)
def emp_id(self,id):
print("employee id is",id)
def emp_name(self,name):
print("employee name is",name)
class company(Employee):-----------------------------(Child class)
def com_id(self,id):
print("company id is",id)
def com_name(self,name):
print("company name is",name)
class client(company):-----------------------------------(Child class)
def cl_name(self,name):
print("client name is",name)
cl=client()
cl.emp_id(9999)
cl.emp_name("antrow")
cl.com_id(1)
cl.com_name("google")
cl.cl_name("mano")
Multiple inheritance
Multiple inheritance have multi parent class and single class.

| Multiple Inheritance |
Example:
class Employee:--------------------------------------(Parent class)
def emp_id(self,id):
print("employee id is",id)
def emp_name(self,name):
print("employee name is",name)
class company:----------------------------------------(parent class)
def com_id(self,id):
print("company id is",id)
def com_name(self,name):
print("company name is",name)
class client(Employee,company):-------------------(Child class)
def cl_name(self,name):
print("client name is",name)
cl=client()
cl.emp_id(9999)
cl.emp_name("antrow")
cl.com_id(1)
cl.com_name("google")
cl.cl_name("mano")
Hierarchical inheritance:
Hierarchical inheritance have single parent class and multi child class |
| Hierarchical Inheritance |
Example:
class Employee:----------------------------------------(parent class)
def emp_id(self,id):
print("employee id is",id)
def emp_name(self,name):
print("employee name is",name)
class company(Employee):---------------------------(child class)
def com_id(self,id):
print("company id is",id)
def com_name(self,name):
print("company name is",name)
c=company()
c.emp_id(999)
c.emp_name("antrow")
c.com_id(1)
c.com_name("google")
class client(Employee):-------------------------------(child class)
def cl_name(self,name):
print("client name is",name)
cl=client()
cl.emp_id(999)
cl.emp_name("antrow")
cl.cl_name("mano")
Hybrid inheritance:
Hybrid inheritance have two parent class and multi child class in our example.
 |
| Hybrid Inheritance |
Example:
class A:----------------------------------------------(parent class)
def m1(self):
print("hey")
class B:-----------------------------------------------(parent class)
def m2(self):
print("hi")
class C(A,B):
def m3(self):
print("antrow")
class D(C):-------------------------------------------(child class)
def m4(self):
print("mano")
b=D()
b.m1()
b.m2()
b.m3()
b.m4()
class E(C):-------------------------------------------(child class)
def m5(self):
print("python")
b=E()
b.m1()
b.m2()
b.m3()
b.m5()
