Hangman游戏大小写匹配错误及单词列表转小写技术求助

要实现忽略大小写的字母判定，只需统一目标单词和用户输入的大小写基准，同时优化输入验证逻辑，以下是具体修改步骤：

1. 统一目标单词的大小写 #

在main()函数中，将随机选中的单词转换为全小写用于匹配判断，同时保留原单词副本用于游戏结束时展示：

def main():
    global count
    global display
    global word
    global original_word  # 新增全局变量保存原单词
    global already_guessed
    global length
    global play_game
    selected_word = random.choice(word_list)
    word = selected_word.lower()  # 转小写作为匹配基准
    original_word = selected_word  # 保留原单词用于最终展示
    length = len(word)
    count = 0
    display = '_' * length
    already_guessed = []
    play_game = ""

2. 统一用户输入的大小写 #

在hangman()函数中，将用户输入的猜测字母转换为全小写，确保和目标单词的基准一致：

guess = input("This is the Hangman Word: " + display + " Enter your guess: \n")
guess = guess.strip().lower()  # 统一转为小写

3. 修正输入验证逻辑 #

原代码中guess <= "9"的判断逻辑有误，替换为更准确的数字检测：

if len(guess) == 0 or len(guess) >= 2 or guess.isdigit():
    print("Invalid Input, Try a letter\n")
    hangman()

4. 优化多字母匹配与显示 #

原代码仅替换第一个匹配的字母，新增循环处理所有相同字母，同时显示原单词的大小写：

elif guess in word:
    already_guessed.extend([guess])
    # 循环替换所有匹配的字母
    while guess in word:
        index = word.find(guess)
        word = word[:index] + "_" + word[index + 1:]
        display = display[:index] + original_word[index] + display[index + 1:]  # 显示原单词的大小写
    print(display + "\n")

5. 修正游戏结束时的单词展示 #

原代码展示正确单词的逻辑错误，改为使用保存的原单词：

elif count == 9:
    time.sleep(1)
    print("   _____ \n"
          "  |     | \n"
          "  |     |\n"
          "  |     | \n"
          "  |     O \n"
          "  |    /|\\ \n"
          "  |    / \\ \n"
          "__|__\n")
    print("Wrong guess. You are hanged!!!\n")
    print("The word was:", original_word)  # 展示原单词
    play_loop()

# Initial Steps to invite in the game:
print("\nWelcome to Hangman!\n")
name = input("Enter Your name: ")
print("Hello " + name + "! Good Luck!")
time.sleep(2)
print("The Game is About to Start!\n Let's Play Hangman!")
time.sleep(3)
