Write а pоlymоrphic functiоn cаlled poly() thаt receives an object (which can be of type Child1 or Child2). The function should concatenate the return value from method1 and method2. Finally it will return the result. Remember to copy your answer into the text box. Code for objects.py: class Superclass: def __init__(self,x): self.x = x def method1(self): return self.x def method2(self): self.x += self.x return self.x def to_string(self): s = str(self.x) return sclass Subclass1(Superclass): def __init__(self, num): super().__init__(num)class Subclass2 (Superclass): def __init__(self, num): super().__init__(num) Code for main.py from cisc108 import assert_equalfrom objects import Subclass1, Subclass2#put your code hereassert_equal(poly(Subclass1("Happy")),"HappyHappyHappyHappy")assert_equal(poly(Subclass2([1,2,3])),[1,2,3,1,2,3,1,2,3,1,2,3])
