python列表、元组、字典练习题

列表，元组，字典练习
#1 元素分类
  有如下值集合[11,22,33,44,55,66,77,88,99,90], 将所有大于66的值保存至字典的第一个key中，将小于66值保存至第二个key的值中。

list = [11,22,33,44,55,66,77,88,99,90]
dic = {}
first = []
second = []
for i in list:
    if i > 66:
        first.append(i)
    elif i < 66:
        second.append(i)
dic['k1']=first
dic['k2']=second
# dic.update(k1=first,k2=second)
print(dic)

2.要求用户输入总资产，例如：2000。显示商品列表，让用户根据序号选择商品，加入购物车购买，如果商品总额大于总资产，提示余额不足，否则，购买成功。

goods = [
    {"name":"电脑","price":1999},
    {"name":"鼠标","price":10},
    {"name":"游艇","price":20},
    {"name":"美女","price":998},
]
ass = int(input("请输入你的总资产："))
dic = {}
num = 1
for i in goods:
    n = i["name"]
    dic.update({num : n})
    num += 1
print(dic)

zm = 0
while True:
    m = int(input("请输入您想要的商品序号（按数字0）结束："))
    if m < 0:
        print("输入错误，请重新输入：")
        m = int(input("请输入您想要的商品序号（按数字0）结束："))
    elif m == 0:
        break

    n = dic.get(m)
    print("您想要购买的是 ",n)
    li = [0,1999,10,20,998]
    print("它的价格为：%d",li[m])
    price = int(li[m])
    zm += price

if zm > ass:
    print("余额不足，请去充值")
else:
    print("购买成功！")
