Python文本冒险游戏物品获取功能故障排查求助

核心问题 #

1. 函数定义语法错误：main()定义前缺少def关键字，直接运行会触发语法错误。
2. 拾取逻辑嵌套错误：处理Get命令的代码被放在了if command in rooms[players_room]（判断是否为房间移动指令）的分支里，但Get Notepad并不是房间方向键，导致这段代码永远不会被执行。
3. Inventory存储逻辑错误：当前用房间名称作为字典键存储物品，玩家切换房间后无法查看已拾取的全部物品，应该改为用列表存储所有拾取的物品。
4. 命令格式化问题：使用capitalize()会把输入的Get Notepad转为Get notepad，虽不影响startswith判断，但统一用小写处理更稳妥，避免大小写输入导致的识别问题。

修复后的完整代码 #

def main():
    while True:
        players_room = "Kitchen"
        inventory = []  # 改为列表存储所有拾取的物品

        print(
            "Welcome to Barbie’s Dream House! Collect six items to help Barbie defeat the brainwashing Ken by using "
            "the directions North, South, East, and West to move between the rooms. To add to inventory, "
            "type: Get 'item name'. Good luck!")

        rooms = {
            "Kitchen": {"East": "Pool", "South": "Dining Room"},
            "Pool": {"item": "Ken"},
            "Dining Room": {"South": "Living Room", "West": "Bathroom", "East": "Bedroom", "item": "Notepad"},
            "Bathroom": {"East": "Dining Room", "item": "Hairspray"},

            command = input('Enter your move: ').strip()
            command_low = command.lower()  # 统一转为小写处理，避免大小写问题

            # 先处理拾取物品命令

                actual_dir = next(dir for dir in rooms[players_room] if dir.lower() == command_low)
                players_room = rooms[players_room][actual_dir]

        if collected_count == 6:  # 除了Ken之外的6个物品
            print("Congratulations! You have collected all six items! You helped Barbie defeat the brainwashing Ken!")

if __name__ == "__main__":
    main()

关键修改点说明 #

• 补全main函数定义的def关键字，修复语法错误。
• 将Get命令的处理逻辑移到最前面，优先判断拾取指令，不再嵌套在移动逻辑里。
• 将inventory从字典改为列表，存储玩家拾取的所有物品，切换房间后仍能显示全部物品。
• 统一用小写处理命令输入，避免大小写输入导致的识别错误，同时保留物品名称的原始大小写显示。
• 修正物品收集完成的判断逻辑，确保只有收集完6个非Ken的物品后才触发胜利条件。
