Question

我的elif语句中的语法无效，为什么会出现代码：

while correct_turns != len(word):
        if correct_turns == len(word):
            finish()
        guess = input("Please guess a letter from above: ")
        elif guess in word and not LettersUnused:
            used_letter(guess,display,LettersUnused)
        elif guess in word and LettersUnused:
            correct(guess,display,correct_turns,LettersUnused)
        elif guess in LettersUnused and not word:
            incorrect(guess,display,LettersUnused)
        elif guess not in LettersUnused:
            used_letter(guess,display,LettersUnused)
        elif len(guess)>1:
            guess_word(guess)

Answer 1

根据您的缩进，您的第一个elif应该只是if。无论如何elif与第一个if无关。

Answer 2

您不需要初始if，因为您的while循环条件会阻止循环输入。

你无法继续＆＃39;继续＆＃39;一个if块，中间有另一条线。将第一个elif更改为if以启动新块;您也可以删除其他if语句，因为它永远不会执行。

while correct_turns != len(word):
    guess = input("Please guess a letter from above: ")
    if guess in word and not LettersUnused:
        used_letter(guess,display,LettersUnused)
    elif guess in word and LettersUnused:
        correct(guess,display,correct_turns,LettersUnused)
    elif guess in LettersUnused and not word:
        incorrect(guess,display,LettersUnused)
    elif guess not in LettersUnused:
        used_letter(guess,display,LettersUnused)
    elif len(guess)>1:
        guess_word(guess)
