Python实现购物车程序

Python  /  管理员 发布于 7年前   211

本文实例为大家分享了程序：Python购物车程序，具体内容如下

需求：

• 启动程序后，让用户输入工资，然后打印商品列表
• 允许用户根据商品编号购买商品
• 用户选择商品后，检测余额是否够，够就直接扣款，不够就提醒
• 可随时退出，退出时，打印已购买商品和余额
• 如余额不足，可充值 

代码：

#coding=utf-8#Version:python 3.6.0#Tools:Pycharm 2017.3.2_date_ = '2018/4/16/016 14:50'_author_ = 'Hongyong'salary = int(input("Please input your salary: "))shoppingmart = []items = (["1","Huawei","￥",2800],     ["2","Earphone","￥",300],     ["3","Book","￥",80])msg_items = '''----------items----------1. Huawei   ￥ 28002. Earphone  ￥ 3003. Book    ￥ 80-------------------------'''print(msg_items)while True:  shopindex = int(input("Please choose goods: "))  if salary > items[shopindex-1][3]:    shoppingmart.append(items[shopindex-1])    salary -= int(items[shopindex-1][3])    print("You have bought {name} !".format(name = items[shopindex-1][1]))    print("Your balance is: ￥",salary)    decision = input("Do you want to quit now?")    print(msg_items)  else:    print("Your balance is not enough! Please try sth else.")    recharge_ans = input("Do you want to recharge?")    if recharge_ans == "y":      recharge = int(input("Please input money: "))      print("Please wait for a while...")      salary += recharge      print("You have recharged successfully!")      print("And the balance is: ",salary,"now!")    decision = input("Do you want to quit now?")    print(msg_items)  if decision == "q":    break  else:    continueprint("You have bought: ",shoppingmart)print("Your balance is: ￥",salary)print("Welcome your next coming!") 

程序效果：

Please input your salary: 0 ----------items----------1. Huawei   ￥ 28002. Earphone  ￥ 3003. Book    ￥ 80------------------------- Please choose goods: 1Your balance is not enough! Please try sth else.Do you want to recharge?yPlease input money: 30000Please wait for a while...You have recharged successfully!And the balance is: 30000 now!Do you want to quit now? ----------items----------1.
