Question

所以我一直在用Python修改Hangman，但遇到了一个问题。输出完全没有更新。尽管代码的其他部分（例如尝试次数减少或已使用的字母添加到used列表中）的功能似乎完美无缺，但它始终保持着下划线网格。

代码如下：

# IMPORT GUARDS
from random import choice
from os import system
from time import sleep

# DECLARATIONS
wordList = ["apple", "pear"]
gameWord = choice(wordList)

strList = list(gameWord)
strOut = "_" * len(gameWord)

tries = 5
used = []

alphabet = "abcdefghijklmnopqrstuvwxyz"

while True:

    system ("cls")
    print (strOut + "\n")
    print ("Tries Left:", str(tries))
    print ("Letters Used:", used)

    Ltr = input ("Letter: ")

    # INPUT CHECK
    if len(Ltr) != 1 and Ltr.lower() in alphabet:
        print ("Input is of incorect size.")
        sleep(0.5)

    elif len(Ltr) == 0 and Ltr.lower() in alphabet:
        print ("No input value given.")
        sleep(0.5)

    if len(Ltr) == 1 and Ltr.lower() not in alphabet:
        print ("Invalid character input.")
        sleep(0.5)

    if len(Ltr) != 1 and Ltr.lower() not in alphabet:
        print ("Input is both too large and contains invalid characters.")
        sleep(0.5)

    # CORRECT INPUT
    if len(Ltr) == 1 and Ltr.lower() in alphabet:

        ltrPos = ( [pos for pos, char in enumerate(gameWord) if char == Ltr.lower])

        # DECLARATIONS
        Counter = 0
        strcounter = 0

        # CHECKING THE NUM OF TIMES THE INPUT APPEARS IN THE WORD
        while Counter < len(strList):
            if gameWord[Counter].lower() == Ltr.lower():
                strcounter += 1
            Counter += 1

        # INPUT DOES APPEAR
        if strcounter != 0:
            strcounter -= 1
            strOut = list(strOut)

            for i in ltrPos:
                strOut[ltrPos[strcounter]] = Ltr.upper()
                strcounter += 1

            strOut = "".join(strOut)

        # INPUT DOES NOT APPEAR AND/OR IS USED
        elif strcounter == 0:
            if Ltr not in used:
                print ("Letter not in word.")
                used.append(Ltr.lower())
                tries -= 1
            else:
                print ("Letter Already Used.")
                sleep(0.5)

        # OUT OF TRIES
        if tries == 0:
            system("cls")
            print ("Game Over. \nWord: " + gameWord)
            break

        # VICTORY
        if "_" not in strOut:
            system("cls")
            print ("Congratulations!")
            break

system ("pause")

感谢所有建议。预先感谢。

主要问题是您忘记在一个地方调用lower函数：

    ltrPos = [pos for pos, char in enumerate(gameWord) if char == Ltr.lower()]

但是还有更多。首先，您可以将strCounter简化为

    strcounter = len(ltrPos)

或者只检查if ltrPos:而不是if strcounter != 0:。另外，您可以使用else代替elif。

下一个问题是strOut[ltrPos[strcounter]]。在这里，您尝试访问lrtPos[strcounter]，当您将strcounter递减一次时会产生索引错误，而不是将其设置回零。相反，只需直接迭代ltrPos中的索引：

        for i in ltrPos:
            strOut[i] = Ltr.upper()

此外，请注意，如果单词中的字母不是，则仅将字母添加到used列表中。
