Python2.7之列表

列表、元组、字典是python中重要的三个数据类型（我是这么认为的），一个一个来吧

列表（list）：可以在列表中添加、删除、修改元素

>>>namelist = ["Tom","Jhon","Smith"]    //长度为3个元素

>>>print namelist

["Tom","Jhon","Smith"]

----------------------------------------------------------------------------

>>>namelist.append("Linda")   //在namelist追加元素到末尾

>>>print namelist

["Tom","Jhon","Smith","Linda"]

--------------------------------------------------------------------------------------

>>>namelist.pop()    //删除namelist末尾的元素

"Linda"

>>>print namelist

["Tom","Jhon","Smith"]

>>>namelist.pop(1)    //删除列表指定位置的元素,列表索引从0开始，若是-1表示逆向索引，从-1开始

'Jhon'

>>>print namelist

["Tom","Smith"]

-----------------------------------------------------

>>>classlist = ["one","two"]

>>>namelist = ["Linda","Tom",classlist,"Jhon"] //相当于包含一个列表的二维列表

>>>print namelist

["Linda","Tom",["one","two"],"Jhon"]
