IT140脚本入门课程：文本游戏无法添加物品至inventory问题求助

核心问题点 #

• 'get'命令逻辑分支错误：当前代码仅在输入get无后续物品名时才处理拾取逻辑，而用户实际输入get item name时params不为空，导致拾取代码完全未执行。
• 物品匹配判断错误：代码中用'item' == room_item做匹配，将固定字符串'item'与房间物品名对比，永远无法匹配成功。
• 物品名拼接问题：输入的物品名可能包含空格（如Fire Spell），直接取params[0]只能拿到第一个单词，无法匹配完整物品名。
• 状态显示错误：player_status函数固定显示Entryway房间，无法正确展示当前所在房间的状态。

关键修复细节 #

• 重构'get'命令逻辑：将拾取逻辑从空参数分支中移出，优先处理带物品名的输入，空参数时仅提示错误并跳过后续逻辑。
• 正确拼接物品名：用' '.join(params).title()将输入的多单词物品名拼接完整，并统一首字母大写，与房间内物品名格式对齐。
• 修正匹配条件：用用户输入的物品名与房间内实际物品名对比，替换原有的无效字符串对比。
• 修复状态显示：让player_status函数使用全局的player_room变量，正确展示当前所在房间的状态。
