Inheritance means deriving properties of one class into another class.
The class whose properties are being derived is called as Parent Class or Super Class or Base class . And class which derives the properties of base class is called as Child Class or Sub Class or Derived Class.
Syntax :
class BaseClass:
.....
.....
class DerivedClass(BaseClass):
.....
.....- Single Inheritance
- Multilevel Inheritance
- Multiple Inheritance
- Hierarchical Inheritance
Single inheritance means,when a derived class derives one base class.
💻 Example :
class A:
def showA(self):
print("I am showA")
class B(A):
def showB(self):
print(" I am showB")
obj=B()
obj.showA()⚙️ Output:
I am showA
Multilevel Inheritance means When a derived class become base class of another class .
💻 Example :
class A:
def showA(self):
print("This is show A")
class B(A):
def showB(self):
print("This is show B")
class C(B):
def showC(self):
print("This is show C")
obj=C()
obj.showA()
obj.showB()
obj.showC()⚙️ Output:
This is show A
This is show B
This is show C
When a class can be derived from more than one base class this type of inheritance is called multiple inheritance.
💻 Example :
class Mother:
def showMotherName(self):
print("Mother Name is ABC")
class Father:
def shoWFatherName(self):
print("Father Name is XYZ")
class child(Mother,Father):
def showChildName(self):
print("I am Child")
obj=child()
obj.shoWFatherName()
obj.showMotherName()
obj.showChildName()⚙️ Output:
Father Name is XYZ
Mother Name is ABC
I am Child
When more than one derived classes are created from a single base this type of inheritance is called hierarchical inheritance.
💻 Example :
class Parent:
def showParent(self):
print("Mother Name : PQR")
print("Father Name : XYZ")
class A(Parent):
def showName(self):
print("A")
class B(Parent):
def showName(self):
print("B")
objA=A()
objA.showName()
objA.showParent()
objB=B()
objB.showName()
objB.showParent()⚙️ Output:
A
Mother Name : PQR
Father Name : XYZ
B
Mother Name : PQR
Father Name : XYZ
