The document discusses inheritance in Python. Inheritance allows a child class to inherit properties from a parent class. There are different types of inheritance including single, multi-level, multiple, and hierarchical inheritance. Single inheritance involves one parent and one child class, multi-level involves multiple generations of inheritance, multiple involves one child class with multiple parent classes, and hierarchical involves one parent class with multiple child classes. Examples of each type of inheritance in Python are provided.

DEFINITION OF INHERITANCE
 When we define a class that inherits all the
properties of other class called inheritance.

SYNTAX OF INHERITANCE
class class_name1:
properties
Class class_name2(class_name1):
properties
Class class_namen:
properties

EXAMPLE OF INHERITANCE
Class father: #parent class
#properties
Class son(Father): #parent class
#properties

EXAMPLE OF INHERITANCE
Class Father:
def lands(self): output
print(“having 15 ekar lands”) having 10 lakhmoney
Class son(Father): having 10 ekar lands
def money(self):
print(“having 10 lakh money”)
s = son()
s.money()
s.lands()

SOME IMPORTANT POINT
 When we create object of child class then we can access child
class and parent class properties.
 But when we create object of parent class then we can’t access
child class properties.

TYPES OF INHERITANCE
1. Single inheritance
2. Multiple inheritance
3. Multi-level inheritance
4. Hierarchical inheritance

SINGLE INHERITANCE
Single inheritance is nothing but which contains only
one parent class and child class.
Parent--class
Child --class

Example of single inheritance
Class A:
num1= int(input(“Enter 1st no:”)
num2= int(input(“Enter 2st no:”)
def Add(self):
print(“Addition:”,self.num1 + self.num2)
def Sub(self):
print(“Subtraction:”,self.num1 - self.num2)

Class B(A):
def Multi(self):
print(“Multiplication:”,self.num1* self.num2)
def Div(self):
print(“Division:”,self.num1/ self.num2)
Obj = B( )
Obj.Add( )
Obj.Sub( )
Obj.Multi( )
Obj.Div( )

MULTI - LEVEL INHERITANCE
In this inheritance we have one parent class and multiple child
class.
parent--class
Child--class
Child--class

SYNTAX OF MULTI - LEVEL INHERITANCE
Class parent:
#properties
Class child1(parent):
#properties
Class child2(child1):
#properties

Example of multi-level inheritance
Class Father:
surname = “singh”
Class Son(Father):
def show(self):
print(“Ajeet”, self.surname)
Class grandDaughter(Son):
def display(self):
print(“Priya”,self.surname)
S = Son( )
S .show( )
S1 =grandDaughter( )
S1.display( )
S1.show( )
Output
Ajeet singh
Priya singh
Ajeet singh

MULTIPLE INHERITANCE
Multiple inheritance which contains more parents class and
only one child class.
Parent--class Parent--class
Parent--class
Child--class

Example of multiple inheritance
Class A:
a=50
b=30
def sum(self):
print(“sum=“, self.a + self.b)
Class B:
def sub(self):
print(“sub=“, self.a – self.b)
Class C:
def Mul(self):
print(“mul=“,self.a * self.b)
Class D(A,B,C):
def show(self):
print(“successful”)

Example of multiple inheritance
Obj = D()
Obj.sum()
Obj.sub()
Obj.Mul()
Obj.show()
Output
Sum=80
Sub=20
Mul=1500
successful

HIERARCHICAL INHERITANCE
Hierarchical inheritance contains only one parent class and
multiple child classes but each child class can access
parent class property.
Parent--class
Child--class Child--class

Example of hierarchical inheritance
Class Father:
surname = “singh”
def show(self):
print(“my surname is”,self.surname)
Class son(Father):
def name(self):
print(“my name is Ajay kumar”, self.surname)
Class Daughter(Father):
def display(self):
print(“my name is Nisha”,self.surname)

Example of hierarchical inheritance
S = son( )
D=Daughter( )
S.name( )
D.display( )
Output
My name is Ajay kumar singh
My name is Nisha singh

12. MULTI - LEVEL INHERITANCE In this inheritance we have one parent class and multiple child class. parent--class Child--class Child--class

13. SYNTAX OF MULTI - LEVEL INHERITANCE Class parent: #properties Class child1(parent): #properties Class child2(child1): #properties

14.

17. Example of multiple inheritance Obj = D() Obj.sum() Obj.sub() Obj.Mul() Obj.show() Output Sum=80 Sub=20 Mul=1500 successful

19. Example of hierarchical inheritance Class Father: surname = “singh” def show(self): print(“my surname is”,self.surname) Class son(Father): def name(self): print(“my name is Ajay kumar”, self.surname) Class Daughter(Father): def display(self): print(“my name is Nisha”,self.surname)

20. Example of hierarchical inheritance S = son( ) D=Daughter( ) S.name( ) D.display( ) Output My name is Ajay kumar singh My name is Nisha singh
