Python文本游戏Inventory功能故障求助：去重与交互逻辑优化

问题排查 #

原代码存在以下核心问题：

• get item命令被错误嵌套在移动指令分支中，永远无法触发
• 房间物品存储为列表，但判断时用字符串'none'对比，逻辑失效
• 缺少当前房间物品提示，玩家无法知晓可拾取物品
• 无拾取确认交互，也未实现非药水物品的重复拾取限制

修复优化后的代码 #

    print("To move type: north, south, east, or west.")
    print("To pick up items type 'get item'.")
    print("To stop playing type 'quit'.")

关键修改说明 #

• 调整物品存储结构：将房间的item从列表改为单个字符串/None，简化判断逻辑
• 修正指令分支：将get item指令从移动分支中移出，单独处理，确保能被触发
• 添加物品提示：进入房间后自动显示当前存在的可拾取物品
• 实现拾取交互：询问玩家是否确认拾取物品
• 重复拾取限制：非药水物品已在背包中时，禁止再次拾取；拾取后清空房间物品，避免重复触发
• 优化指令提示：在说明中添加get item指令的使用提示
