Multi level inheritance in python

• Implementing inheritance with more than level is called Multi Level Inheritance.
• We can access the complete functionality of all objects using Child object reference.

class Grand:
    def m1(self):
        print("Grand Parent m1()")
        return

class Parent(Grand):
    def m2(self):
        super().fun()
        print("Parent m2()")
        return

class Child(Parent):
    def m3(self):
        super().fun()
        print("Child m3()")
        return
    
class Inheritance:
    def main():
        c = Child()
        c.m1()
		c.m2()
		c.m3()

		p = Parent()
		p.m1()
		p.m2()
		p.m3() # error

		g = Grand()
		g.m1()
		g.m2() #error
		g.m3() #error
        return

Inheritance.main()
