Python實作購物車程式

這篇文章主要為大家詳細介紹了Python實現購物車程序，具有一定的參考價值，有興趣的小伙伴們可以參考一下

本文實例為大家分享了程序：Python購物車程序，具體內容如下

需求：

• 啟動程序後，讓使用者輸入薪資，然後列印商品清單

• #允許用戶依商品編號購買商品

• 用戶選擇商品後，偵測餘額是否夠，夠就直接扣款，不夠就提醒

• #隨時可退出，退出時，印製已購買商品及餘額

• 如餘額不足，可儲值 

代碼：

#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!")

程式效果：
