y = PhysicianRobot("James")
y.say_hi()

Example 2: inheritence in python

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...')
