python classes and inheritance code example

Example 1: python inheritance

class Person:  
    name = ""  

    def __init__(self, personName):  
        self.name = personName  
  
    def showName(self):  
        print(self.name)  
  
class Student(Person): 				# Student inherits from Person superclass
    studentClass = ""  

    def __init__(self, studentName, studentClass):  
        Person.__init__(self, studentName)		# superclass constructor
        self.studentClass = studentClass  		# Student class specific
  
    def getStudentClass(self):  
        return self.studentClass  
  
  
person1 = Person("Dave")
person1.showName()                  # Dave
student1 = Student("Mary", "Maths")
print(student1.getStudentClass())   # Maths
student1.showName()                 # Mary

Example 2: 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 3: inheritence in python

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()

Example 4: how to inherit a class in python

class Bird():
        def eat(self):
                print ("eating")
 
class Sparrow(Bird):
        def sound(self):
                print ("ChiChi!")
 
birdobj = Sparrow()
birdobj.eat()
birdobj.sound()
