Python 3.x 使用OOP方法创建用户名的Python代码。

我试图使用两个不同的类创建一个代码，一个叫做User，它存储关于用户的信息。user类的属性为_username、_wins、_ties和_loss。使用int的方法，获取\u用户名、获取\u用户\u胜利、设置\u用户\u胜利、获取\u用户\u失败、设置\u用户\u失败、获取\u用户\u联系、设置\u用户\u联系和显示\u用户。另一个类称为Users，它存储并显示一个user\u对象。然后是另一个同时使用类和菜单的程序；[1] 创建用户，[2]显示用户，[3]退出

我对如何让它工作感到困惑，我试图编写的代码，谁能帮我弄清楚如何编写这样的代码

import Users
import random
#User Class
class User:
    def __init__(self, username, wins, ties, losses):
        self._username = username
        self._wins = wins
        self._ties = random.randint(0,10)
        self._losses = random.randint(0,10)
    #Returns value of username field 
    def get_username(self):
        return self._username
    #Returns value of wins field
    def get_user_wins(self):
        return self._wins
    #Returns vaule of ties fied
    def get_user_ties(self):
        return self._ties
    #Returns the value of losses field
    def get_user_losses(self):
        return self._losses
    #Displays the username and stats
    def display_users(self):
        print("User List")
        print("---------")
        for user in (users.create_user()):
            print("Username: ", get_username())
            print("Wins\tTies\tLosses")   
            print(str(get_user_wins())+"\t"+str(get_user_ties())+"\t"+str(get_user_losses( )))

class Users:
    def __init__(self, user_list):
        self._user_list = []
    def create_user(self):
        username = input("Please enter the user name: ")
        wins = int(input("How many wins does "+username+" have? "))
        ties = 0
        losses = 0
        self._created_user = User.User(username, wins, ties, losses)
        self._user_list.append(self._created_user) 
        return self._user_list
