利用python实现购物车功能
要求:
(推荐学习:Python入门教程)
1、启动程序后让用户输入余额,并打印商品列表
2、用户通过输入编号购买商品
3、用户选择商品购买后,根据余额判断成功或者失败,给出对应提示
4、可以随时退出,退出后打印账号余额以及购买的商品列表
思路:
1、首先,用户余额需要进行存储,用户购买的物品需要进行存储在数组中
2、用户购买成功后,将购买的物品放入物品集合,并用总金额减去余额
3、如果失败,给出失败提示,并打印余额
4、用户选择继续后,无论成功失败,都可以继续购买
代码实现:
# 用户输入工资 balance = int(input("Please input balance:")) # 定义衣服的数组 clothes = [["pants",100],["T-shirt",50],["skirt",20]] # 个人所得,包括金钱和获取的物品 haveGoods = [balance,[]] flag = True while flag: # 打印衣服列表 print("The clothes list is as follows") print("______clothesList______") i = 1; for c in clothes: print('The number:',i,":",c) i += 1 # 用户输入商品编号 code = int(input("Please choose the number:")) # 判断钱是否够用 if clothes[code-1][1] <= haveGoods[0]: # 在自己的购物清单中加入已购物品 haveGoods[1].append(clothes[code-1]) # 减去花费的金钱 haveGoods[0] -= clothes[code-1][1] print("You have successfully purchased!") print("Your account balance is:",haveGoods[0]) else: print("Your account balance is insufficient!") print("Your account balance is:",haveGoods[0]) judge = input("You can press any button to continue,or input 'n' to leave:") if judge == "n": flag = False print("Your account balance is:",haveGoods[0]) print("Your shopping list is as follows:") print("______clothesList______") for h in haveGoods[1]: print(h)
