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 ￥ 2800
2. earphone ￥ 300
3. 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:
continue
print("you have bought: ",shoppingmart)
print("your balance is: ￥",salary)
print("welcome your next coming!")
