列表，元祖，字典的使用

列表，元祖，字典的使用

列表中大于66的值添加到字典的K1中小于66的值添加到字典k2中

a = [11,22,33,44,55,66,77,88,99,90]
dict ={
    "k1":[],"k2":[]
}
for i in a :
    if i > 66:
        dict["k1"].append(i)
    else:
        dict["k2"].append(i)
print dict

列表的使用

li = ["alec","anc","Alex","Tony","rain"]
tu = ("alec","anc","Alex","Tony","rain")
dic = {"k1":"alec","k2":"anc","k3":"Alex","k4":"Tony","k5":"rain"}
for item in dic.values():
    if item.upper().startswith("A") and item.upper().endswith("C"):
        print item

输出商品列表，用户输入序号，显示用户的选中的商品

li = ["手机","电脑","鼠标","游艇"]
for key, item in enumerate(li,1):
    print key, item
a = input("请输出商品序号：")
inp = int(a)
print li[a-1]
