我是 python 新手，需要我编写的一段代码的帮助。截至目前，我的程序功能齐全，但是我无法让难度功能按预期工作。我有多个 .txt 文档，其中的单词难度不同。我希望用户能够选择他们将玩的难度。目前，当我尝试运行该程序时，我收到一条错误消息，提示“未定义单词”。任何帮助是极大的赞赏

一个可能的问题是您尝试读取目标文件两次，而您从未在第一次关闭它。考虑只读取一次输入文件：

while True:
    difficulty = int(input("""choose your difficulty,
    1 = EASY
    2 = INTERMEDIATE
    3 = HARD
    4 = VERY HARD
    5 = INSANE"""))

    if difficulty >= 1 and difficult <= 5:
        break
    else:
        print("Please enter a difficulty level of 1 to 5")

word = random.choice(open("Level"(difficulty).txt).read().split())

此外，input()返回一个字符串，因此如果您想将difficulty视为整数，则将结果从input().

在这里，您尝试将难度附加到“级别”字符串。

word = (random.choice(open("Level"(difficulty).txt).read().split()))

你可以试试这样的

word = (random.choice(open("Level{0}.txt".format(difficulty)).read().split()))

实际获得您期望的文件名。

有了这个，你也可以删除

if difficulty == X:

部分，但您需要注意检查您尝试使用用户输入打开的文件是否确实存在。

而且您还需要查看您的 checkLetter 方法，因为该行

guess_word[word.index(c)] = c

只会更改guess_word 字符串中正确字母的第一次出现（如果该字母出现不止一次，可能会多次出现）。您需要获取正确字母的每次出现的位置。

您正在尝试将一个单词读两遍。将 if 语句中的行替换为： word=(random.choice(open("Level1.txt").read().split())) 不要忘记在 if-elif 块之前声明 'word'。并删除 if 语句末尾的行。 word = (random.choice(open("Level"(difficulty).txt).read().split())) 此外，按照其他答案中的建议将输入视为字符串。这应该根据我的工作
