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，移动空格，并查找以a或A开投并且以c结尾的所有元素。
li = ["alec"," aric","Alex","Tony","rain"]
tu = ("alec"," aric","Alex","Tony","rain")
dic = {"k1":" alec","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，提示账号余额不足，否则，购买成功。
附加：可充值，某商品移除购物车
一、
#!/usr/bin/env python
#-*- coding:utf-8 -*-
new1 = []
new2 = []
Ks = {"k1":"None","k2":"None"}
Li = [11,22,33,44,55,66,77,88,99,90]
for item in Li:
if int(item) > 66:
new1.append(item)
Ks.update({‘k1‘:new1})
else:
new2.append(item)
Ks.update({‘k2‘: new2})
print(Ks)
二、
#!/usr/bin/env python
#-*- coding:utf-8 -*-
li = ["alec", " aric", "Alex", "Tony", "rain"]
tu = ("alec", " aric", "Alex", "Tony", "rain")
dic = {"k1": " alec", "k2": "aric", "k3": "Alex", "k4": "Tony"}
Cz1 = input("请输入要查找的元素：")
if Cz1 in li:
print("True")
else:
print("False")
三、
#!/usr/bin/env python
#-*- coding:utf-8 -*-
Li = [‘手机‘,‘电脑‘,‘鼠标垫‘,‘游艇‘]
for n,Me in enumerate(Li,1):
print(n,"-",Me)
try:
shop = input("请输入商品序对应列号：\n")
print("您选择的商品是:%s"%Li[int(shop)-1])
except Exception:
print("没有此商品！！")
