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()
    if info == '':
        print('无人注册会员请先注册')
        return
    user_dict = open_mode.to_info_dict('用户注册信息.txt')
    if not login_name[0]:
        while true:
            print(38*'-')
            print('输入q可以退出登入程序')
            user_name = input('请输入你的名字\n')
            if user_name =='q':
                return false
            if user_name not in user_dict:
                print('账号不存在请重新登入')
                continue
            print(38*'-')
            user_pwd = input('请输入你账号密码\n')
            if user_pwd != user_dict[user_name][0]:
                print('密码错误请重新登入')

                continue

            login_name[0] = user_name
            return  true
    while true:
        print(38*'-')
        print("\033[0;40;46m\t\t欢迎使用登入功能\t\t\t\033[0m")
        print(f'账号{login_name[0]}已经登入')
        chiose = input('输入1当前账号退出并退出登入程序\n'
                       '输入2当前账号退出并重新登入程序\n'

            login()
            return

            return true
        else:

2.注册

                          '(账号大于6位小于9位由纯字母组成)\n'
                         )
        if user_name=='q':

        elif len(user_name.replace(' ','')) != len(user_name):
            print('输入的账号有空格请重洗输入')
            continue

            continue
        print(38*'-')
        user_pwd = input('请输入密码\n'
