如何根据用户响应实现Python命令行Wordle程序重启

问题说明 #

需要为命令行版本Wordle猜词游戏增加对局结束后询问玩家是否继续的功能，玩家确认后自动开启新局。此前尝试调整缩进、封装函数、添加while循环的方式均出现运行无输出的问题，原有代码如下：

import random
from colorama import Fore, Back, Style
    
print("Guess My Word - Based on TextBasedWordle by DrVictor")
print("")
    
def processGuess(theAnswer, theGuess):
    position = 0
    clue = ""
    for letter in theGuess:
        if letter == theAnswer[position]:
            clue += u"\u2714 "
        elif letter in theAnswer:
            clue += Fore.YELLOW + u"\uFF0D " + Style.RESET_ALL
        else:
            clue += Fore.RED + u"\u274C " + Style.RESET_ALL
        position += 1
    print(clue)
    print("")
    return clue == u"\u2714 "u"\u2714 "u"\u2714 "u"\u2714 "u"\u2714 " # true if correct, false otherwise
    
# load words and store them into a list
word_list = []
word_file = open("target_words.txt")
for word in word_file:
    word_list.append(word.strip())
    
# pick a word
answer = random.choice(word_list)

num_of_guesses = 0
guessed_correctly = False
 
while num_of_guesses < 6 and not guessed_correctly:
  
    # get guess from user
    guess = input("Input a 5-letter word and press enter: ")
    print("You have guessed", guess)
    num_of_guesses += 1
    print(6 - num_of_guesses, "guesses remaining")
    
    # process guess
    guessed_correctly = processGuess(answer, guess)
    
# display end of game message
if guessed_correctly:
    print("Congratulations, you guessed the word correctly with", num_of_guesses, "guesses.")
else:
    print("You have used up all your guesses. The correct word was", answer)

故障原因 #

此前实现失败的核心问题是没有拆分全局逻辑和单局逻辑：随机选答案、初始化猜词计数、猜词循环这些单局专属逻辑直接写在全局作用域，只会在程序启动时执行一次；外层新增循环时如果没有把这些单局初始化逻辑放进循环体，就会出现要么不循环、要么循环时变量状态异常导致无输出的问题。

修复后代码 #

核心改动点：

• 把单局完整流程封装为run_single_game()函数，每调用一次就开启全新对局
• 最外层增加主循环，对局结束后询问玩家意愿，输入y则重开，输入n则退出
• 补充输入合法性校验，避免异常输入打断程序
• 优化文件读取写法，避免文件句柄泄漏
• 简化猜对判断逻辑，避免硬编码拼接符号容易出错的问题

import random

# 欢迎信息仅在程序启动时打印一次
print("Guess My Word - Based on TextBasedWordle by DrVictor")
print("")

def processGuess(theAnswer, theGuess):
    position = 0
    clue = ""
    for letter in theGuess:
        if letter == theAnswer[position]:
            clue += u"\u2714 "
        elif letter in theAnswer:
            clue += Fore.YELLOW + u"\uFF0D " + Style.RESET_ALL
        else:
            clue += Fore.RED + u"\u274C " + Style.RESET_ALL
        position += 1
    print(clue)
    print("")
    # 清除颜色转义字符后判断是否全对，避免硬编码拼接出错
    plain_clue = clue.replace(Fore.YELLOW, "").replace(Fore.RED, "").replace(Style.RESET_ALL, "").strip()
    return plain_clue == u"\u2714 \u2714 \u2714 \u2714 \u2714"

def run_single_game(word_list):
    # 每局重新随机选答案、重置猜词计数
    answer = random.choice(word_list)
    num_of_guesses = 0
    guessed_correctly = False

    while num_of_guesses < 6 and not guessed_correctly:
        guess = input("Input a 5-letter word and press enter: ").strip()
        # 输入长度校验，不符合要求直接重输，不扣猜词次数
        while len(guess) != 5:
            guess = input("Invalid input, please enter a 5-letter word: ").strip()
        print(f"You have guessed {guess}")
        num_of_guesses += 1
        print(f"{6 - num_of_guesses} guesses remaining")

        guessed_correctly = processGuess(answer, guess)

    # 单局结算
    if guessed_correctly:
        print(f"Congratulations, you guessed the word correctly with {num_of_guesses} guesses.")
    else:
        print(f"You have used up all your guesses. The correct word was {answer}")

if __name__ == "__main__":
    # 词表仅在程序启动时加载一次，无需每局重复读文件
    word_list = []
    # 用上下文管理自动关闭文件
    with open("target_words.txt", "r", encoding="utf-8") as f:
        for word in f:
            stripped_word = word.strip()
            if len(stripped_word) == 5: # 过滤词表中不符合长度的异常行
                word_list.append(stripped_word)
    
    # 主循环控制重开逻辑
    while True:
        run_single_game(word_list)
        # 校验重开输入
        while True:
            play_again = input("Start a new game? (y/n): ").strip().lower()
            if play_again in ["y", "n"]:
                break
            print("Invalid input, please enter y or n")
        if play_again == "n":
            print("Game over, thanks for playing!")
            break
