Hangman Revealing双打不起作用？

Question

所以我有这个刽子手代码...再次，在此先感谢，它一个接一个地显示单词并且工作正常，但是当有多个单词时，例如两个l＆＃39; s中的hello和两个p＆＃ 39;在苹果中它只显示一个而不是两个。我不知道为什么会这样，而且我已经做了一些谷歌润滑，所得到的是枚举，但我已经尝试过无济于事。 这是代码：

def hangman():
    global fullWordList
    fullWordList = []
    global wrongnums
    wrongnums =[]
    print("What is the word to be guessed?")
    print("Words means that there are no numbers")
    global guessnum
    guessnum=input('>')
    fullWord = guessnum
    for line in fullWord:
      for c in line:
        fullWordList.append(c)
        print (fullWordList)
    print("how many chances?")
    global chances
    chances=int(input('>'))
    print("game in beginning")
#    sleep(5)
#    print ("\n" * 100)
    global blanks
    blanks = '_ ' * len(guessnum)
    print()
    print(blanks)
    guessing()

def guessing():
    global fullWordList
    global chances
    print("guess a letter")
    global guess
    guess=input('>')
    guessloop()

def guessloop():
    global chances
    if guess in fullWordList:
        if guess in fullWordList:
            letterIndex = guessnum.index(guess)
            global blanks
            blanks = blanks[:letterIndex*2] + guess + blanks[letterIndex*2+1:]
            fullWordList.remove(guess);
            global lenWord
            lenWord = len(fullWordList)
            print (fullWordList)
            print (lenWord)
            print ("Guess is correct!")
            if guess in fullWordList:
                guessloop()

            else:
                wrongnums.append(guess)
                print (wrongnums)
                if lenWord == 0:
                    print() 
                    print("Word: ",blanks)
                    win()

                else:
                    print() 
                    print("Word: ",blanks)
                    guessing()

        else:

            if lenWord == 0:
                win()

            else:
                print() 
                print("Word: ",blanks)
                guessing()

    elif guess in wrongnums:
        print("You've guessed that!")
        guessing()

    else:
        chances -=1
        wrongnums.append(guess)
        print (wrongnums)
        print ("Guess is wrong! ", chances, " more failed attempts allowed.")
        if chances == 0:
          gameOver()

        else:
          guessing()

def check():    
    print() 
    print("Word: ",newBlanks)
    guessing2()

def win():
  print("You guessed it well done")
  print("Would you like to play again?")
  PG = input(">")
  if PG == "yes" or PG == "Y" or PG == "Yes" or PG == "yea" or PG == "Yea":
    print ("Game will restart in 5 seconds")
    sleep(5)
    hangman()

  else:
    print("Going to main menu in 5 seconds")
    sleep(5)
    start()

def gameOver():
  print("You ran out of guesses, sorry, you lose")
  print("Would you like to play again?")
  PG = input(">")
  if PG == "yes" or PG == "Y" or PG == "Yes" or PG == "yea" or PG == "Yea":
    print ("Game will restart in 5 seconds")
    sleep(5)
    hangman()

  else:
    print("Going to main menu in 5 seconds")
    sleep(5)
    start()

现在我也有了一个代码：

def hangman():
    global fullWordList
    fullWordList = []
    global wrongnums
    wrongnums =[]
    print("What is the word to be guessed?")
    print("Words means that there are no numbers")
    global guessnum
    guessnum=input('>')
    fullWord = guessnum
    for line in fullWord:
      for c in line:
        fullWordList.append(c)
        print (fullWordList)
    print("how many chances?")
    global chances
    chances=int(input('>'))
    print("game in beginning")
#    sleep(5)
#    print ("\n" * 100)
    global blanks
    blanks = '_ ' * len(guessnum)
    print()
    print(blanks)
    guessing()

def guessing():
    global fullWordList
    global chances
    print("guess a letter")
    global guess
    guess=input('>')
    guessloop()

def guessloop():
    global chances
    if guess in fullWordList:
        if guess in fullWordList:
            letterIndex = guessnum.index(guess)
            global blanks
            guesses = (guessnum)
            guesses = blanks[letterIndex]
            blanks[letterIndex] = guess
            fullWordList.remove(guess);
            global lenWord
            lenWord = len(fullWordList)
            print (fullWordList)
            print (lenWord)
            print ("Guess is correct!")
            if guess in fullWordList:
                guessloop()

            else:
                wrongnums.append(guess)
                print (wrongnums)
                if lenWord == 0:
                    print() 
                    print("Word: ",blanks)
                    win()

                else:
                    print() 
                    print("Word: ",blanks)
                    guessing()

        else:

            if lenWord == 0:
                win()

            else:
                print() 
                print("Word: ",blanks)
                guessing()

    elif guess in wrongnums:
        print("You've guessed that!")
        guessing()

    else:
        chances -=1
        wrongnums.append(guess)
        print (wrongnums)
        print ("Guess is wrong! ", chances, " more failed attempts allowed.")
        if chances == 0:
          gameOver()

        else:
          guessing()

def check():    
    print() 
    print("Word: ",newBlanks)
    guessing2()

def win():
  print("You guessed it well done")
  print("Would you like to play again?")
  PG = input(">")
  if PG == "yes" or PG == "Y" or PG == "Yes" or PG == "yea" or PG == "Yea":
    print ("Game will restart in 5 seconds")
    sleep(5)
    hangman()

  else:
    print("Going to main menu in 5 seconds")
    sleep(5)
    start()

def gameOver():
  print("You ran out of guesses, sorry, you lose")
  print("Would you like to play again?")

    sleep(5)
    hangman()

  else:
    print("Going to main menu in 5 seconds")
    sleep(5)
    start()


hangman()

这是我编辑它并得到这个错误：

blanks[letterIndex] = guess
TypeError: 'str' object does not support item assignment

我真的很难过，我希望这有足够的数据来帮助。

我尝试尽可能少地更改您的代码，但我需要让代码完全运行以解决所有错误，所以我正在分享我对您的代码所做的事情。

你已经确定了两个问题 - 一个是只要有一个匹配，程序就会继续下一个猜测，而不会检查多个正面命中。

第二个问题是你得到的错误是'blanks'是一个字符串，你试图更改特定索引处的字符（第二个代码示例的第43行：blanks[letterIndex] = guess）。字符串是不可变的，因此无法尝试更改字符。围绕这个的方法不止一种 - 我跟（下面）一起将'空白'设置为列表，允许您更改列表中的任何元素（因为列表是可变的）。要向用户显示列表，请尝试''.join(blanks)从列表中生成可显示的字符串。

我对代码进行了一些更改（再次，尝试尊重您的结构和样式）以提出有效的方法：

1. 删除了变量guessnum（你只需要fullWord）
2. 将'blanks'从字符串转换为列表 - 现在您可以在猜测正确时进行更改。这与您提出的问题直接相关。
3. 简化了猜测函数中if ... else语句的流程，经历了三种可能的结果：正确猜测，重复猜测和错误猜测。在那些是一些子检查（如果正确，它是一个胜利？如果不正确，这是一个损失？）我包括一些评论，所以你可以看到做了什么改变和在哪里。
4. 当猜测正确时，对于发生的每场比赛，“空白”都会相应更新。 （并使用'.join（空格）显示空格以生成元素的字符串。）当猜测正确时，fullWordList也会针对发生的每个匹配进行更新 - 字母将替换为' - '。所以现在检查win是否fullWordList只包含' - '元素。

仍然没有例外，但是这里有什么用'苹果'这样的词 - 试图赢，输，重复猜测。

希望它有所帮助 - 让我知道是否有一些不明确的事情。我不想只是重新编写代码，而是希望通过一种方法解决问题。

还可以进行其他改进，但这至少可以解决你的障碍。
