else if statement in python always provides the same result [closed]

I am working on an exercise to learn Python. The aim is to print out either 0, 20 or 100 based on an input, but the statement always gives me a "100":

x = input("what is your greeting?").lowerx = str(x)y = x.startswith("h")if "hello" not in x and y == "True":  print("20")if x == "hello":  print("0")else:  print("100")

I do not understand why.
