Python小游戏代码无法返回商店菜单，求助帮忙修复代码问题

原代码核心问题 #

• 缩进错误：Python依赖缩进划分代码块，原代码中while循环、条件判断的从属代码未正确缩进，逻辑无法按预期执行
• 循环条件逻辑错误：原代码定义Shop = ["Shop"]，将response not in Shop作为循环条件，用户输入的yes/no永远无法匹配该值，循环逻辑完全失效
• 语法错误：长字符串跨行未做拼接处理，直接运行会触发报错
• 金币计算逻辑错误：每次购买硬编码从1000扣除，未读取当前Coins变量的实际值，多次购买时数值计算错误
• 分支逻辑错误：判断用户输入no的分支被错误缩进在购买逻辑内，永远无法被触发
• 缺少回到商店菜单的循环逻辑：购买完成后没有跳转回商品选择页面的对应处理

修复后完整代码 #

import time

CharacterHealth = 100
Coins = 1000
Sword = ["Diamond", "Metal", "Wood"]

print("Hello! Welcome to my game! This is an extremely fun action game! I hope you enjoy!\n")
time.sleep(2)
name = input("Please enter your username.\nUsername: \033[1;32;40m")
print("\033[1;37;40mHello, " + name + ". Would you like to enter a shop?\nYou can purchase swords!\n")
time.sleep(2)

while True:
    # 外层循环：询问是否进入商店
    response = input("\033[1;37;40mWould you like to enter the shop?(yes/no)\nSelection: \033[1;32;40m").lower()
    if response == "yes":
        # 内层循环：商店商品菜单，操作完成后自动回到该菜单
        while True:
            answer = input(f"\n\033[1;37;40mYou have {Coins} coins. Would you like to buy:\n(a) Diamond sword [Costs 900]\n(b) Metal Sword [500]\n(c) Wooden sword [200]\n(d) Back\nSelection: \033[1;32;40m").lower()
            if answer == "a":
                if Coins >= 900:
                    Coins -= 900
                    input(f"{name}\033[1;37;40m, you currently have {Coins} Coins! Press any key to return to shop menu.")
                else:
                    input(f"{name}\033[1;37;40m, your coins are not enough! Press any key to return to shop menu.")
            elif answer == "b":
                if Coins >= 500:
                    Coins -= 500
                    input(f"{name}\033[1;37;40m, you currently have {Coins} Coins! Press any key to return to shop menu.")
                else:
                    input(f"{name}\033[1;37;40m, your coins are not enough! Press any key to return to shop menu.")
            elif answer == "c":
                if Coins >= 200:
                    Coins -= 200
                    input(f"{name}\033[1;37;40m, you currently have {Coins} Coins! Press any key to return to shop menu.")
                else:
                    input(f"{name}\033[1;37;40m, your coins are not enough! Press any key to return to shop menu.")
            elif answer == "d":
                print("You exit the shop.\n")
                time.sleep(2)
                # 退出内层循环，回到外层是否进入商店的询问
                break
    elif response == "no":
        print("You exit the shop.")
        print("You enter your house.")
        # 退出外层循环，结束流程
        break
    else:
        print("Invalid input, please enter yes or no.")

效果说明 #

• 购买任意商品完成后，按下任意键会自动回到商店商品选择菜单
• 新增金币不足校验，避免出现负金币的异常情况
• 所有输入统一转为小写判断，无需区分大小写输入
• 选择d退出商店后，会回到是否进入商店的询问，选择no即可退出商店进入房屋流程
