I have a program that prompts the user for a guess on a guessing game, and I need the program to keep the values stored some how in order to prevent the user from guessing again.
For instance if a user inputs 'a' for the first guess and 'b' for the second, I need the program to store these and tell tell the user that they have already been used.
Guesses are always single characters. I am not allowed to use lists, dictionaries, or sets.
I know that i should concatenate the strings, but other than I'm clueless. I want to use a if statement or a function but not sure how to set those up.
I am also thinking that i need something like
variable += variable
As mentioned in the comments, you should really be using a set. Here's how to do it with string concatenation though.
guesses = "" guess = input("guess: ") if guess in guesses: print("already used") else: guesses += guess
