You could try something like this class Room: def __init__(self): self.l=int(input("enter length of room != ")) self.b= int(input("enter breath of room = ")) self.h =int(input("enter height of room = ")) def area(self): a = 2*(self.l * self.b)+2*(self.h * self.b)+2*(self.h * self.l) return a class Paint: def __init__(self): self.amt = int(input("enter cost per meter square = ")) class Cost(): def totalcost(self): c = Room().area() * Paint().amt print("total cost to paint a room = ",c) def area(self): return Room().area() c1 = Cost()
