36 Multi Level inheritance in python

 '''

1. We can inherit a derived class from another derived class, 

this process is known as multilevel inheritance

2. Example :- We have three classes A, B and C, 

If you inheritance class A into class B and class B into class C This is called 

Multi Level inheritance.

'''

class A():

    def add(self, a, b):

        print('sum is', a + b)

    def sub(self, a, b):

        print('sub is', a - b)

class B(A):

    def colour(self):

        print('Blue')

class C(B):

    pass

ins = C()

print(dir(ins))

#ins.colour()
