Python inheritance class code example

Example 1: what is a child inheritance in python with example

# =============================================================================
# Inhertance
# =============================================================================
class A:
    def feature1(self):
        print('Feature 1 in process...')
    def feature2(self):
        print('Feature 2 in process...')       #Pt.1
        
class B:
    def feature3(self):
        print('Feature 3 in process...')
    def feature4(self):
        print ('Feature 4 in process...')
        
a1 = A() 

a1.feature1()
a1.feature2()

a2 = B()

a2.feature3()
a2.feature4()
# THE ABOVE PROGRAM IS A PROGRAM WITHOUT USING INHERITANCE
        
# WITH THE USE OF INHERITANCE IS BELOW
class A:
    def feature1(self):
        print('Feature 1 in process...')    
    def feature2(self):
        print('Feature 2 in process...')
        
class B(A):
    def feature3(self):
        print('Feature 3 in process...')    # Pt.2
    def feature4(self):
        print ('Feature 4 in process...')
        
a1 = A() 

a1.feature1()
a1.feature2()

a2 = B()

a2.feature3()
a2.feature4()


# NOW TO CHECK OUT THE DIFFERENCE BETWEEN Pt.1
# AND Pt.2 TRY RUNNIG THE CODE ON THE BASIS OF
# INHERITANCE, IN OTHER WORDS TRY RUNNING ONLY 
# B CLASS IN Pt.2 AND THEN RUN ONLY a2
# YOU WILL SEE A DIFFERENCE IN THE RUNNING OF 
# ONLY a2,,,, IT WILL STILL SHOW THAT FEATURE 3
# AND 4 IS IN PROCESS,, THIS MEANS THAT B IS THE

Example 2: inheritance in python

# creating parent class
class Parent:
    BloodGroup = 'A'
    Gender = 'Male'
    Hobby = 'Chess'
    
# creating child class
class Child(Parent): # inheriting parent class
    BloodGroup = 'A+'
    Gender = 'Female
    
    def print_data():
        print(BloodGroup, Gender, Hobby)
    
# creating object for child class
child1 = Child()
# as child1 inherits it's parent's hobby printed data would be it's parent's
child1.print_data()

Example 3: Inheritance example python

class Parent:

    def abc(self):
        print("Parent")

class LeftChild(Parent):

    def pqr(self):
        print("Left Child")

class RightChild(Parent):

    def stu(self):
        print("Right Child")

class GrandChild(LeftChild,RightChild):

    def xyz(self):
        print("Grand Child")

obj1 = LeftChild()
obj2 = RightChild()
obj3 = GrandChild()
obj1.abc()
obj2.abc()
obj3.abc()

Example 4: inheritence in python

# =============================================================================
# Inhertance
# =============================================================================
class A:
    def feature1(self):
        print('Feature 1 in process...')
    def feature2(self):
        print('Feature 2 in process...')       #Pt.1
        
class B:
    def feature3(self):
        print('Feature 3 in process...')
    def feature4(self):
        print ('Feature 4 in process...')
        
a1 = A() 

a1.feature1()
a1.feature2()

a2 = B()

a2.feature3()
a2.feature4()
# THE ABOVE PROGRAM IS A PROGRAM WITHOUT USING INHERITANCE
        
# WITH THE USE OF INHERITANCE IS BELOW
class A:
    def feature1(self):
        print('Feature 1 in process...')    
    def feature2(self):
        print('Feature 2 in process...')
        
class B(A):
    def feature3(self):
        print('Feature 3 in process...')    # Pt.2
    def feature4(self):
        print ('Feature 4 in process...')
        
a1 = A() 

a1.feature1()
a1.feature2()

a2 = B()

a2.feature3()
