Learn Python the hard way, ex39 列表的操作

 #!/usr/bin/python
 #coding:utf-8

 ten_things = "apples oranges crows telephone light sugar"
 print "wait there's not 10 things in that list,let's fix that"

 stuff = ten_things.split(' ')  #10个东西，以' '间隔开
 more_stuff = ["day","night","song","frisbee","corn","banana","girl","boy"]  #更多的原料

 while len(stuff) != 10:  #取得List stuff的长度，当不等于10时循环
     next_one = more_stuff.pop()    #截取more_stuff的最后一个元素（默认值）
     print "adding:",next_one    #输出pop取得的值
     stuff.append(next_one)     #使用append将之前截取的值赋予list：stuff
     print "there's %d items now" % len(stuff)

 print "there we go : ",stuff

 print "let's do some things with stuff"

 print stuff[1]  #第二个元素，list从0计数
 print stuff[-1]  #whoa!fancy   最后一个元素(-1)
 print stuff.pop()
 print ' '.join(stuff)  #what?cool!
 print '#'.join(stuff[3:5])  # super stellar

Output:

 wait there's not 10 things in that list,let's fix that
 adding: boy
 there's 7 items now
 adding: girl
 there's 8 items now
 adding: banana
 there's 9 items now
 adding: corn
 there's 10 items now
 there we go :  ['apples', 'oranges', 'crows', 'telephone', 'light', 'sugar', 'boy', 'girl', 'banana', 'corn']
 let's do some things with stuff
