Python文本游戏移动方向功能异常，请求定位错误代码行

我是Python初学者（刚上第一节课），这是我的期末项目——一款基于文本的Python游戏。目前游戏的退出和拾取物品功能正常，但移动方向功能存在问题，无法正常运行。我曾尝试修改rooms字典和directions集合的格式来匹配，但仍未解决问题，恳请帮忙定位错误代码行并提供指导。

rooms={
'Locker Room': {'go South':'Storage Room', 'go West': 'Coaches Office', 'go North': 'Teachers Lounge', 'go East': 'Concession Stand', 'Item': 'gym clothes'},
'Storage Room':{'go North':'Locker Room','go East':'Cafeteria','Item': 'basketballs'},
'Cafeteria':{'go West':'Storage Room', 'Item': 'sports drinks'},

我曾尝试修改rooms字典中的方向格式，并调整directions集合内容，但问题仍未解决。
