dict

一、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 的值保存至第二个key的值中。 即： {'k1': 大于66的所有值, 'k2': 小于66的所有值}

二、查找

查找列表中元素，移除每个元素的空格，并查找以 a或A开头 并且以 c 结尾的所有元素。

li = ["alec", " aric", "Alex", "Tony", "rain"]
tu = ("alec", " aric", "Alex", "Tony", "rain")
dic = {'k1': "alex", 'k2': ' aric',  "k3": "Alex", "k4": "Tony"}
 

三、输出商品列表，用户输入序号，显示用户选中的商品

商品 li = ["手机", "电脑", '鼠标垫', '游艇']

四、购物车

功能要求：

•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，提示账户余额不足，否则，购买成功。

•附加：可充值、某商品移除购物车
