python - 没有显示任何错误的刽子手游戏，但是终端没有显示任何内容

Question

import random
from Words import words
import string

def get_valid_word(words):
    word = random.choice(words)
    while '-' or ' ' in word:
        word = random.choice(words)
    return word.upper()


def hangman() -> object:
    word = get_valid_word(words)
    word_letter = set(word)
    alphabet = set(string.ascii_uppercase)
    used_letter = set()

    while len(word) > 0:
        print("You have used these letter", ' '.join(used_letter))
        word_list = [letter if letter in used_letter else '-' for letter in word]
        print("Current word: ", ' '.join(word_list))
        user_letter = input("Guess a letter: ")

        if user_letter in alphabet - used_letter:
            used_letter.add(user_letter)
            if user_letter in word_letter:
                word_letter.remove(user_letter)
        elif user_letter in used_letter:
            print("You have already used this letter: ")
        else:
            print("Invalid input")


if __name__ == '__main__':
    hangman() 

我无法使用代码来执行函数 hangman()。终端仅显示以下输出:

问题似乎出在线路上

while '-' or ' ' in word:

您的语法略有偏差，这意味着这将始终评估为 True，因此代码此时进入无限循环

python 将上面的解释为

while ('-') or (' ' in word):

因此字符串 - 是 or 语句的一半，任何非空字符串的计算结果总是 True将 while 条件保留为:

while True or ' ' in words:

试试这个:

while '-' in word or ' ' in word:
