定义一个网络用户类User包含用户idid、用户名username用户密码password、email地址emailAdrr四个私有化成员变量和一个属于类的用户总人数totalUser 1请定义一个含有用户IDID、用户密码password两个参数的构造器完成三个实例成员变量的初始化其中email地址emailAdrr是用户名加上字符串gameschoolcom。 2请利用上述构造器在main

class User:
    totalUser = 0
    
    def __init__(self, id, password):
        self.id = id
        self.password = password
        self.username = "user" + str(id)
        self.emailAdrr = self.username + "@gameschool.com"
        User.totalUser += 1

user1 = User(1, "123456")
user2 = User(2, "abcdef")
user3 = User(3, "qwerty")

print("用户总人数：", User.totalUser)
