我在編寫一個名為**ve**e* App的程序應用程序用於管理用戶信息每個用戶都有一個唯一的用戶ID和姓名用戶可以登錄、註冊和修改個人信息我已完成並進行一些測試然後在最後的測試中，我發現一個問題當用戶嘗試修改姓名時，有時會發生姓名重複的情況即兩個不同的用戶的姓名，變成了相同的現在產生問題是有時候可以正確檢測到重複，有時候就會漏掉是否我函數部份搞錯(? 還是..... 新手努力摸索還在寫碼測試~請多包涵 ******e* App def __init__(self): self.users = {} def register_user(self, user_id, name): if user_id in self.users: print("User ID already exists.
