Question

我遇到一个错误：“ tuple”对象的以下代码没有属性“ first_name”。我完全被困住了

class User:
    """Summarizes User Profile"""
    def __init__(self,first_name, last_name, followers, following):
        self.first_name = first_name
        self.last_name = last_name
        self.followers = followers
        self.following = following
        self.fullname = first_name + " " + last_name

    def describe_user(self):

         print(self.fullname + " has " + followers + " and follows " + following + " users")

    def greet_user(self):
        """Greets user"""
        print("Welcome back, " + self.fullname)

#User info
user1 = ("Krish","Patel",100, 200)
user2 = ("Bob","Smith",2032, 153)

User.describe_user(user1)

Answer 1

您实际上需要实例化一个User对象，而不仅仅是一个tuple。试试

user1 = User("Krish","Patel",100, 200)
user2 = User("Bob","Smith",2032, 153)

在这种情况下，“元组”对象没有属性“ first_name”是什么意思？
