python3倒叙字符串

google测试工程师的一道题：
设计一个函数，使用任意语言，完成以下功能：
一个句子，将句子中的单词全部倒排过来，但单词的字母顺序不变。比如，This is a real world,输出结果为
world real a is this.

下面利用python来实现：

句子为：

 1 #!/usr/bin/env python3.4
 2 # -*- coding: utf-8 -*-
 3
 4 #某一段文字
 5 data = "You don’t need us to tell you that China’s Internet space is booming. With the world’s largest Internet user population—686 million as of January 2016—and a long way to go to reach Internet penetration levels of developed countries, China’s Internet industry is growing in both scale and influence. And as more and more Chinese users come online, Baidu continues to innovate to meet their changing needs and diverse tastes. We aim to serve the needs of our users and customers with products and solutions that prioritize the user experience and reflect our corporate culture – simple and reliable."

 7 #按照空格分割
 8 strings = data.split()
 9 arr = []
10
11 #打印出来
12 for string in strings:
13     arr.append(string)
14
15 #将文本倒叙
16 arr.reverse()
17 # 按照空格将文本变为字符串
18 newstring = " ".join(arr)
19
20 print(newstring)

结果：
