Python游戏Bug排查：living_room()无法启动及房间切换失效

核心问题分析 #

1. 默认启动房间错误：start()函数里初始Location被设为"attic"，导致默认进入阁楼。
2. 房间切换无效：每个房间函数内的Location、Inventory、Gamewon等都是局部变量，修改后不会同步到start()的全局状态，导致切换后状态不更新。
3. 其他隐性问题：living_room()的循环条件大小写不匹配（"Living room" vs "living room"），且每次循环重置Inventory导致物品丢失；跨房间状态（如Mouse、Hole）无法共享。

start()

关键修改点说明 #

• 默认启动房间修正：start()里初始Location改为"living room"，符合需求。
• 状态变量共享：每个房间函数接收Inventory、Hole、Mouse作为参数，执行后返回更新后的状态（包括新位置和游戏胜利状态），确保start()能同步状态。
• 循环条件修复：living_room()的循环条件改为Location == "living room"（统一小写，匹配变量值），确保循环正常执行。
• 物品状态保留：移除房间函数内的Inventory = ""重置代码，捡起的物品会持续保留。
• 输入处理优化：将用户输入转为小写（.lower()），避免大小写输入导致的识别错误。
• 逻辑补全：修复了奶酪与字符串共存时的物品状态处理，以及喂老鼠后的物品移除逻辑，让游戏流程更合理。
