Python 使用正则表达式 将一段英文文本切割成 单词列表，使用的语法是：
re.split(r"\b[\.,\s\n\r\n]+?\b",str)
代码如下：
import re
str=‘‘I still have it on my note 3 and holding pretty good,
I have also dropped my phone about 3 times
and the case has done it‘s job, so I am very happy with the case,
plus it feels very nice on the hand,
and I like that the camera don‘t touch the outside anymore.
happy customer here..‘‘
if __name__ == ‘__main__‘:
word_list=re.split(r"\b[\.,\s\n\r\n]+?\b",str)
for word in word_list:
print word
