I have a multiple choice question but I want the code to tell the user that there input is wrong if they have inputted an invalid answer:

Ive used a != statement which has only worked for single answer questions:

if drinkselect != "cola":

print("Not on our menu!\n")

Any help would be appreciated!

while True:

  delivery=input("input......")
  if delivery == "yes":
     print("yes....")
     
  elif delivery == "no":
     print("no...")
     
  else:
      print("invalid input....")
