Python 使用正則表達式 將一段英文文本切割成 單詞列表，使用的語法是：
re.split(r"\b[\.,\s\n\r\n]+?\b",str)
代碼如下：
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
