Attempting to code the Mastermind game which involves the creation of a hidden colour combination or code - consisting of 4 colour code chosen from 6 colours by the program. The user is the code-breaker and tries to figure out the code by guessing the code. The program then gives feedback on the correctness of the guess by telling the second player how many correctly positioned in their guessed colour code has and how many correct colour but incorrectly positioned colours the guess has, until the user either guesses the actual colour code or runs out of their 10 tries.

I'm having trouble with the print_game function and the valid function

Also I'm not sure how to command the actual program to function like a game after the if__name__ == 'main' section. As in calling the actual functions to giving commands to the user to see their progress.

Any help is much appreciated.

Answer 1

If you want to ask the user for input, you can use raw_input in Python 2.X, and input in Python 3. I would start with that in order to test your code.

valid seems conceptually correct to me except for the pass statement at the end which is unnecessary. It can be rewritten simply as:

valid(user_guess, valid_chars, size):
    return len(user_guess) == size and reduce(operator.and , map(lambda x: x in valid_chars ,user_guess))

I am not sure what you are trying to achieve with print_game. Given a list of guesses and clues print_game should just be:

print_game(guesses,clues):
    print ('Guesses \t Clues')
    assert len(guesses) == len(clues)
    for g,c in zip(guesses,clues):
        print g,'\t',c
