而不是在我的刽子手游戏（python）中使用全局用于我的情况

Question

我想知道是否还有其他方法可以解决我的情况（在我的Hangman游戏中将用户输入（guessword）替换为破折号字符串（单词）而不是使用global。我以前的游戏帖子：How to replace the repeat word in python (Hangman Game)!和How do i detect the repeat input in my hangman game (Python)!这是我的代码： 代码从开始：

def writeCustomwords():
    f = open('custom.txt', 'w')
    words = input("Enter a list of comma separated words:")
    print("Custom words save into custom.txt")
    f.write(words)
    f.close()
def readFileWords():
    if choose == "1":
        txt = open('easy.txt', 'r')
        txt.read()
        txt.close()


    elif choose == "2":
        txt = open('intermediate.txt', 'r')
        txt.read()
        txt.close()

    elif choose == "3":
        txt = open('hard.txt', 'r')
        txt.read()
        txt.close()

    elif choose == "4":
        txt = open('custom.txt', 'r')
        txt.read()
        txt.close()
import random
def getRandomWord():
    if choose == "1":
        with open('easy.txt') as txt:
            word = txt.read().splitlines()
        random_word = random.choice(word)
        print(random_word)
        print("\nThere are", len(random_word),"letters in this word")
    elif choose == "2":
        with open('intermediate.txt') as txt:
            word = txt.read().splitlines()
        random_word =  random.choice(word)

       print("\nThere are", len(random_word),"letters in this word")
    elif choose == "3":
        with open('hard.txt') as txt:
            word = txt.read().splitlines()
        random_word = random.choice(word)

        print("\nThere are", len(random_word),"letters in this word")
    elif choose == "4":
        with open('custom.txt') as txt:
            word = txt.read().split(",")
        random_word = random.choice(word)
        print(random_word)
        print("\nThere are", len(random_word)-random_word.count(" "),"letters in this word")
    return random_word


def gethiddenWord():

    import re
    guess = getRandomWord().lower()
    guessed = re.sub(r"\S", "-", guess)
    print("\n\t\t\t-----------------------------------------------")
    print("\t\t\tRULES")
    print("\t\t\t-----------------------------------------------")
    print("\n\t\t\tPlease Guess one letter(a-z) at a time!")
    print("\n\t\t\tIf you want to guess the word, please enter '0'")
    print("\n\nThe word is : ",guessed)
    return guess,guessed
def checkValidGuess():
    if len(guessword)==1 and guessword not in guesslist and guessword not in num:
        return True
    elif guessword in guesslist:
        print("You have already guessed that letter")
    elif guessword in num:
        print("You can only input letter a-z")
        print("Try again")
    elif len(guessword) >1:
        print("You can only guess one letter at a time!")
         print("Try again")
def checkPlayerWord():
    if guessall == word:
        return True
    else:
        return False
    return checkp
def checkLetterInWords():
    if guessword.lower() in word:
        return True
    elif guessword.lower() not in word and guessword.lower() not in num:
        return False


def gethiddenWord():

    import re
    guess = getRandomWord().lower()
    guessed = re.sub(r"\S", "-", guess)
    print("\n\t\t\t-----------------------------------------------")
    print("\t\t\tRULES")
    print("\t\t\t-----------------------------------------------")
    print("\n\t\t\tPlease Guess one letter(a-z) at a time!")
    print("\n\t\t\tIf you want to guess the word, please enter '0'")
    print("\n\nThe word is : ",guessed)
    return guess,guessed

我的问题在这里：

def getGuessedWord():
    global words
    for pos,l in enumerate(word): 
        if l==guessword.lower():

            words= words[:pos] + guessword.lower() +words[pos+1:]




    print(words)
    return words

在功能之外

 word,words = gethiddenWord()

我的访问功能的进一步代码：

    choose = input("Enter your choice:")
    readFileWords()
    time =10
    word,words = gethiddenWord()
    count = len(word)-word.count(" ")
    guesslist=[]

 while time !=0 and word:

        print("You have", time, "guesses left.")
        guessword = input("Guess a letter or enter '0''to guess the word: ")

        num = ["1","2","3","4","5","6","7","8","9"]
        valid = checkValidGuess()
        guesslist.append(guessword.lower())


        if guessword =="0":
            guessall = input("What is the word: ")
            checkp = checkPlayerWord()
            del guesslist[0]
            if checkp == True:
                print("Well done! You got the word correct!")
                break
            elif checkp == False:
                print("Uh oh! That is not the word!")
                time -=1
        elif valid== True:
            checkl= checkLetterInWords()
            if checkl == True:
                time -=1
                print("Well done!",guessword,"is in my word")
                count -= word.count(guessword)
                getGuessedWord()
                countfinish = checkFinish()
                if countfinish == True:
                    break
                else:
                    continue

            elif checkl == False:
                time -=1
                print("Uh oh! That letter is not in my word!")

如果没有全球性，我无法解决它。请帮忙！感谢
