python多个字符的分隔

Question

“Natural scene image classification is a very hot topic in the field of computer research, in which image feature extraction is the keypoint. As a texture descriptor of image low-level features, Local Binary Pattern (LBP)‘
找出B这段文字里的”of”, 逗号“,”，点句号”.”，“in”，“and”, “an”，“a”, “in”, “is”，“the”等字符，然后把这段话按这些字符分开

Answer 1

import re
p = re.compile(r'[,.]|\sof\s|\sis\s|\sin\s|\sand\s|\sa\s|\san\s|\sthe\s')
s = 'Natural scene image classification is a very hot topic in the field of computer research, in which image feature extraction is the keypoint. As a texture descriptor of image low-level features, Local Binary Pattern (LBP)'
p.split(s)
['Natural scene image classification', 'a very hot topic', 'the field', 'computer research', '', 'which image feature extraction', 'the keypoint', ' As', 'texture descriptor', 'image low-level features', ' Local Binary Pattern (LBP)']
