Python基于数列实现购物车程序过程详解

# 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)
