为列表创建3个对象并打印

import re
user_list = []
while True:
    if len(user_list) < 3:
        user = input('请输入用户名：')
        pwd = input('请输入密码：')
        email = input('请输入邮箱：')
        check_email = re.compile(r'\w+(@live.com)')
        ret = check_email.match(email)
        if ret:
            class person:
                def __init__(self):
                    self.user = user
                    self.pwd = pwd
                    self.email = email
            obj = person()
            user_list.append(obj)
        else:
            print('邮箱格式有误')
    else:
        for i in user_list:
            print('我叫%s，邮箱是%s' %(i.user, i.email))
        break
