简单的订单系统，使用的os目录

一：主要是是os模板练习案例。

import os
import datetime
import timeDB_PATH = 'db'def history(user_path):if not os.path.exists(user_path):print('无历史记录')returnwith open(user_path, mode='r', encoding='utf-8') as f:for line in f:line = line.strip()print(line)def booking(user_path):while True:location = input('请输入景区，或者输入q/Q,退出订票：')if location.upper().strip() == "Q":breakbook_num = input('输入订几张：')ctime_string = datetime.datetime.now().strftime('%Y-%m-%d-%H:%M:%S')book_string = '{},{},{}\n'.format(location, book_num, ctime_string)with open(user_path, mode='a', encoding='utf-8') as f:f.write(book_string)def run():if not os.path.exists(DB_PATH):os.makedirs(DB_PATH)# 2.user_name = input('请输入用户名：')user_path = os.path.join(DB_PATH, '{}.txt'.format(user_name))if os.path.exists(user_path):print('{}用户已经存在'.format(user_name))else:print('{}用户是新用户'.format(user_name))# 3.func_dict = {'1': history, '2': booking}while True:print('1：是查看历史订单，2：预定')choice = input('请选择功能，或者退出q/Q：')if choice.upper().strip() == 'Q':returnfunc = func_dict.get(choice.strip())if not func:print('序号输入错误')continuefunc(user_path)run()

二：账号注册

import os
import sys
import hashlib
import json
import datetimeDATA_FILE = "user_info.txt"
SALT_STR = "dgd5"def md5(*args):salt_str, user_pwd = argshashlib_md5 = hashlib.md5(salt_str.encode('utf-8'))hashlib_md5.update(user_pwd.encode('utf-8'))pwd_str = hashlib_md5.hexdigest()return pwd_strdef run():while True:flag = 0user_name = input('请输入注册的用户：')if os.path.isfile(DATA_FILE):with open(DATA_FILE, mode='r', encoding='utf-8') as file:for line in file:if user_name in line:print('这个{}用户已经被注册，请重新注册其它账号'.format(user_name))flag = 1breakif flag:continueuser_pwd = input('请输入用户的密码：')user_time = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')pwd_str = md5(SALT_STR, user_pwd)with open(DATA_FILE, mode='a', encoding='utf-8') as file:mesg = "{},{},{}".format(user_name.strip(), pwd_str.strip(), user_time.strip())file.write(mesg)file.write('\n')run()

三：时间有限，后面会补充os目录其它功能
