One mistake in this game, which does not end the game with word "BANANA"

I've tried letter "A" so it shown me _A_A_A , my next quess was B, so obv. BA_A_A, but after that i put in "N" and it says

Guess a letter: n banana Strikes: 6/7

Tried to type "N" again but "Guess a letter: n You've already guessed that letter! banana "

We should fix that problem ;)

It's impossible to tell what's causing the problem without any form of code. If you want help you have to give a better explanation and elaborate on the problem.

:point_right: You might need different logic for detecting a win.

If you're comparing the total number of correct guesses against the length of the word, the program will work for words where all letters are unique (like "branch"), but it will never think you have completed the game when the word has repeated letters (like "banana").

You probably need to revise your logic for detecting a win. You could do something like testing to see if every letter of the word is in the list of correct guesses, for example.

I replaced line 53-59 with the code below and it worked for any word. The for loop compares each letter in a word with the guess in turn and pushes every match into the good_guesses array so the length of the good_guesses array always reflects the number of all letters (including multiple occurrences) that have been figured. In case that the secret word is "banana" and the guess is "n", "n" would be added to good_guesses twice.

        if guess in secret_word:
            for letter in secret_word:
                if guess == letter:         
                    good_guesses.append(guess)
            if len(good_guesses) == len(list(secret_word)):
                print("You win! The word was {}".format(secret_word))
                break
        else:
            bad_guesses.append(guess)

You can not simply compare the length of guesses (known to be unique) with the length of the target word (repeated letters may exist). Hint: One way to find out the length of unique characters in a word is the "length of a set made from the word"
