TypeError:get_first_name（）缺少1个必需的位置参数：'；自我'；用Python

所以我有麻烦显示管理员的名字，出于某种原因，它一直说它不存在，请给我一些反馈什么是错误的，非常感谢 下面您可以找到admin类，我们在其中设置了所有参数，如名字和姓氏等 在那之后，我们得到了bank系统类，我在其中导入了admin类并实例化了它，但仍然没有任何结果，即使添加了缺少的位置参数，它仍然表示fname不存在

class Admin:
    def __init__(self, fname, lname, address, user_name, password, full_rights):
        self.fname = fname
        self.lname = lname
        self.address = address
        self.user_name = user_name 
        self.password = password
        self.full_admin_rights = full_rights

    def update_first_name(self, fname):
        self.fname = fname

    def update_last_name(self, lname):
        self.lname = lname

    def get_first_name(self):
        return self.fname

    def get_last_name(self):
        return self.lname

至少有两个问题：

BankSystem.admin\u login（）

返回由消息和管理对象组成的对，但

run\u main\u options（）

将该对分配给单个变量

admin\u obj

。您应该将其更改为类似于

msg，admin\u obj=…

的内容，以使其行为符合您的预期

BankSystem.admin\u menu（）

覆盖在第一行传递的对象。这条线应该拆下

---

在

BankSystem.admin\u菜单中

：

admin\u obj=admin

-这是

admin

类的别名，而不是

admin

类的实例。有很多代码可以显示您的问题。为了让人们更容易地帮助您，请尝试将代码数量减少到演示问题所需的最低程度。@Krazzy不客气，如果您的问题已解决，请不要忘记标记为已回答；-）
