9-7 管理员

Posted 2021-05-23 拒绝中年危机

1. 项目

管理员是一种特殊的用户。编写一个名为 Admin 的类，让它继承你为
完成练习 9-3 或练习 9-5 而编写的 User 类。添加一个名为 privileges 的属性，用于存
储一个由字符串（如"can add post"、 "can delete post"、 "can ban user"等）组成的
列表。编写一个名为 show_privileges()的方法，它显示管理员的权限。创建一个 Admin
实例，并调用这个方法。

2. 代码

class User():   # 创建User类
    def __init__(self, first_name, last_name, age, address, phone): # 属性
        self.first_name = first_name
        self.last_name = last_name
        self.age = age
        self.address = address
        self.phone = phone
        self.login_attempts = 0 # 添加属性

    def describe_user(self):    # 方法
        print(self.first_name,
              self.last_name,
              self.age,
              self.address,
              self.phone)

    def greet_user(self):   # 方法
        print("How beautiful name " + self.last_name + self.last_name,
              "\\n too young, too simple", "your homeland " + self.address
              + " is a warm place, ", "could you tell me your contact?")

    def increment_login_attempts(self, number1):    # 递增方法
        self.login_attempts += number1  # 值加1
        print("共登录用户量：" + str(self.login_attempts))

    def reset_login_attempts(self, number2):    # 重置方法，重置为0
        self.login_attempts = 0
        print("共登录用户量：" + str(self.login_attempts))

# 创建Admin类
class Admin(User):
    # 初始化父类的属性，在初始化User特有的属性
    def __init__(self, first_name, last_name, age, address, phone):
        super().__init__(first_name, last_name, age, address, phone)
        self.privileges = []    #初始化特有属性

    def show_privileges(self): # 创建方法存储字符串
        for privilege in self.privileges:
            print(privilege)

admin = Admin(\'Kevin\', \'Hou\', 30, \'ShangHai\', 13141516170)
admin.describe_user()
admin.privileges = [\'can add post\', \'can delete post\', \'can ban user\']
admin.show_privileges()
