从7点到9点写的小程序(用了模块导入,python终端颜色显示,用了点局部和全局可变和不可变作用域,模块全是自定义)

未完待续的小程序

要是能做的好看为啥不做的好看

在同目录下生成程序

1.程序文件

run.py

from login import login

from register import register

from balance_enquiry import balance_enquiry

from top_up import top_up

msg_dict ={

    '1':login,

    '0':register,

    '2':top_up,

    '3':balance_enquiry,

    'q':'quit'

}

Login_name = [None]

while True:

    print("\033[0;31;44m\t\t杨大爷超市欢迎您\t\t\t\033[5m")

    print(38*'-')

    print("\033[0;30;42m\t\t输入0进入注册界面\t\t\t\033[5m")

    print("\033[0;30;42m\t\t输入1进入登入界面\t\t\t\033[5m")

    print("\033[0;30;42m\t\t输入2进入充值界面\t\t\t\033[5m")

    print("\033[0;30;42m\t\t输入3进入余额查询界面\t\t\033[5m")

    print("\033[0;30;42m\t\t输入q退出程序 \t\t\t\t\033[5m")

    print(38 * '-')

    user_shopping_chiose = input('请输入你要选择的功能')

    if user_shopping_chiose not in msg_dict:

        print('请好好输入')

        continue

    elif user_shopping_chiose=='q':

        print('再见')

        break

    msg_dict[user_shopping_chiose]()

2.自制文件读取模块

open_mode.py

def read_all(filename):

    with open (filename,'a+',encoding='utf8') as fr :

        fr.seek(0)

        res = fr.read()

    return res

#文件信息格式为info_list=[name:pwd:aggregate score:The remaining points:freeze0为解冻,1为冻结:账户余额 ]

#info_dict[name:[pwd:aggregate score:The remaining points:freeze0为解冻,1为冻结]]

def to_info_dict(filename):

    info_dict = dict()

    with open (filename,'a+',encoding='utf8') as fr :

        fr.seek(0)

        for info in fr:

            info_list = info.strip().split(':')

            name = info_list[0]

            info_dict[name] = info_list[1:]

    return info_dict

#账号:密码:总积分:剩余积分:是否为冻结0为未冻结,1位冻结:账户余额

def add_info(user_name,user_pwd):

    with open('用户注册信息.txt', 'a', encoding='utf8') as fw:

        fw.write(f'{user_name}:{user_pwd}:0:0:0:0\n')

def add_purchase_history(user,goods,nums,price,Discounted_price):

    with open('购买记录.txt', 'a', encoding='utf8') as fw:

        fw.write(f'{user}:{goods}:{nums}:{price}:{Discounted_price}\n')

3..功能模块

1.登入

login.py

import open_mode

#Login_successful[0]来判断是否登入成功

Login_name = [None]

def login():

    print("\033[0;40;46m\t\t欢迎使用登入功能\t\t\t\033[0m")

    info = open_mode.read_all()

        return

    user_dict = open_mode.to_info_dict('用户注册信息.txt')

    if not Login_name[0]:

        while True:

                continue

            print(38*'-')

            user_pwd = input('请输入你账号密码\n')

            if user_pwd != user_dict[user_name][0]:

2.注册
