[Head First Python]1. 初始python-人人都爱列表

 movies = [ "hello", "world",["xin","lover",["Jerry","cat"]]]

 print movies
 print "\n"

 for each_1 in movies:
     if isinstance(each_1,list):
         for each_2 in each_1:
             if isinstance(each_2,list):
                 for each_3 in each_2:
                     print(each_3)
             else:
                 print(each_2)
     else:
         print(each_1)

 def print_lol(the_list):
     for each_item in the_list:
         if isinstance(each_item,list):
             print_lol(each_item)
         else:
             print(each_item)

 print "\n"
 print_lol(movies)

python列表看起来可能像数组, 不过还不只如此, 列表是完备的python集合对象,列表通过列表方法的形式提供一些现成得功能.

 >>> cast = ["hello","world","!!!"]    #创建列表
 >>> print(cast);                    #打印列表 print
 ['hello', 'world', '!!!']
 >>> print(cast[1]);                    #列表类似数组访问
 world
 >>> print(len(cast));                #列表元素个数 len
 3
 >>> cast.append("testadd");            #列表尾添加元素 append
 >>> print(cast)
 ['hello', 'world', '!!!', 'testadd']
 >>> cast.pop()                        #删除列表尾元素 pop
 'testadd'
 >>> print(cast)
 ['hello', 'world', '!!!']
 >>> cast.extend(["ni","hao"])        #添加列表 extend
 >>> print(cast)
 ['hello', 'world', '!!!', 'ni', 'hao']
 >>> cast.remove("!!!")                #删除指定元素 remove
 >>> print(cast)
 ['hello', 'world', 'ni', 'hao']
 >>> cast.insert(0,"test")            #插入指定元素 insert
 >>> print(cast)
 ['test', 'hello', 'world', 'ni', 'hao']
