笨办法学Python ex38

列表操作

• 输入：

# -*- coding: utf-8 -*-

ten_things = "Apples Oranges Crows Telephone Light Sugar"

print "Wait there are not 10 things in that. Let's fix that."

stuff = ten_things.split(' ')# 通过指定分隔符对字符串进行切片成一个列表
more_stuff = ["Day", "Night", "Song", "Frisbee", "Corn", "Banana", "Girl", "Boy"]

while len(stuff) != 10: # 循环条件，如果不是10个字符串则循环，达到10个后停止
    next_one = more_stuff.pop() # 移除列表中的元素（默认最后一个），并返回该元素的值
    print "Adding: ", next_one
    stuff.append(next_one) # 将元素加到stuff列表
    print "There are %d items now." % len(stuff)

print "There we go: ", stuff

print "Let's do some things with stuff."

print stuff[1]
print stuff[-1] # whoa! fancy
print stuff.pop()
print ' '.join(stuff) # what? cool! 用于将序列中的元素以指定的字符连接生成一个新的字符串。
print '#'.join(stuff[3:5]) # super stellar!
