函数_练习题_登录注册游戏抽奖

Posted 2022-11-12 allenchen168

在猜年龄的基础上编写登录、注册方法，并且把猜年龄游戏分函数处理，如

1. 登录函数
2. 注册函数
3. 猜年龄函数
4. 选择奖品函数

思路：根据功能要求划分功能模块，每个功能模块封装一个函数，最后按顺序调用函数，根据每次调用函数后的返回结果判断是否进行下一步

def register():
    """注册功能"""
    count = 0
    while count < 3:
        username_inp = input('请输入你的用户名：')
        pwd_inp = input("请输入你的密码：")
        re_pwd_inp = input("请再次输入你的密码：")

        if not pwd_inp == re_pwd_inp:
            print('两次密码不一致')
            count += 1
            continue

        with open('user_info.txt','a',encoding='utf8') as fa:
            fa.write(f'username_inp:pwd_inp|')  # 用户名和密码用“：”隔开，
            fa.flush()
            return 1

def login():
    """登录功能"""
    username_inp = input("请输入用户名：")
    pwd_inp = input("请输入密码：")

    with open('user_info.txt','r',encoding='utf8') as fr:
        for user_info in fr:
            username, pwd = user_info.split(':')

            if username.strip() == username_inp and pwd.strip('|') == pwd_inp:
                print('登录成功')
                return 1
            else:
                continue  # 一般不会把continue写在最后，在可以不用写
        else:
            print('登录失败')

# 猜年龄游戏
def guess():
    """猜年龄游戏"""
    age = 20
    age_count = 0
    while age_count < 3:
        age_inp = input('请输入你的年龄：')  # 与用户交互

        if not age_inp.isdigit():
            print(f'输入错误，请输入数字')  # f格式化可以拼接数字和字符串
            continue

        age_inp_int = int(age_inp)

        if age_inp_int > age:  # 核心逻辑
            print('猜大了')
        elif age_inp_int < age:
            print('猜小了')
        else:
            print('猜对了')
            return 1
        age_count += 1

def choice():
    """选择奖品"""
    prize_msg = 0:'布娃娃',1:'钢铁侠',2:'nick老师签名',3:'python精品课'
    prize_dict = 
    prize_count = 0
    while prize_count < 2:
        print(f'奖品如下：prize_msg')

        # 与用户交互
        prize_choice =int(input('请选择你需要的奖品序号：'))
        prize = prize_msg[prize_choice]

        # 奖品信息放入购物车
        if prize in prize_dict:
            prize_dict[prize] += 1
        else:
            prize_dict[prize] = 1

        print(f'恭喜你获得奖品prize')

        prize_count += 1

    print(f'总共获得奖品为：prize_dict')

res1 = register()
if res1 == 1 :
    res2 = login()
    if res2 == 1:
        res3 = guess()
        if res3 == 1:
            choice()
