猜python中的文字游戏需要结束

Question

如何结束这场比赛？如果整个单词都猜对了，或者您失去了一生，但如果有人一个个地猜出所有字母，我将无法结束。

secret_word = "something".upper()
lifes = u'\u2764'
total_lifes = 5
print("You have 5 lifes in total to guess the answer")
guess = None
for_list = "?"*len(secret_word)
my_list = list(for_list)

def change_user_output(value):
    for j in range(0, len(secret_word)):
        if (value == secret_word[j]):
            my_list[j] = value
    new_user_output = " ".join(my_list)
    print(new_user_output)

while total_lifes > 0:
    print(lifes * total_lifes)
    print("Guess any letter : ")
    guess = input().upper()
    if(guess == secret_word):
        print("WOW that is correct, the secret word is %s"%secret_word)
        break
    if(guess in secret_word):
        print("You guessed it right %s is in SECRET WORD"%guess)
        change_user_output(guess)
    else:
        print("There is no such letter in the SECRET WORD, you loose a life")
        change_user_output(guess)
        total_lifes -= 1

if total_lifes == 0:
    print("You've lost all lifes, GAME OVER FOR YOU")
    print("The SECRET WORD was : %s"%"".join(secret_word))
