[請益] APP 註冊用戶姓名重複

[cici950630 (沉睡在墓地裡的Classical)]

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. Please register with a different ID
.")
        else:
            self.users[user_id] = name
            print(f"User {user_id} registered successfully with the name {name
}.")

    def login_user(self, user_id):
        if user_id in self.users:
            print(f"Welcome! User {user_id} is logged in with the name {self.u
sers[user_id]}.")
        else:
            print("User ID does not exist. Please register as a new user.")

    def modify_name(self, user_id, new_name):
        if user_id in self.users:
            current_name = self.users[user_id]
            if current_name == new_name:
                print("New name is the same as the current name. Please enter
a different name.")
            else:
                for _, name in self.users.items():
                    if name == new_name:
                        print("Name already exists. Please enter a different n
ame.")
                        break
                else:
                    self.users[user_id] = new_name
                    print(f"User {user_id}'s name has been modified to {new_na
me}.")
        else:
            print("User ID does not exist. Please register as a new user.")


if __name__ == "__main__":
    app = VeeApp()

    app.register_user("001", "Rosa")
    app.register_user("002", "Calii")

    app.login_user("001")
    app.login_user("003")

    app.modify_name("001", "Calii")
    app.modify_name("002", "Rosa")

推 keith222: 你在做更新時有用user id 作為唯一識別
→ keith222: 嗎？
→ bigbearlazir: 資訊太少了 看不出是畫面上重複還是
→ bigbearlazir: 資料真的重複 是app資料還是後端資
→ bigbearlazir: 料
→ bigbearlazir: 沒程式碼就是要別人通靈而已
→ cici950630: 謝謝，我好像弄有點懂了

噓 accessdenied: 要大家花精力幫你猜答案，說自己弄
