//test.py
1 import re
2
3 print (re.match('www', 'www.myweb.com').span())
4 print (re.match('com', 'www.myweb.com'))
5
6 line = 'Cats are smarter than dogs'
7 matchObj = re.match(r'(.*) are (.*?) (.*?) (.+)', line, re.M|re.I)
8 if matchObj:
9 print 'matchObj.group()', matchObj.group()
10 print 'matchObj.group(1)', matchObj.group(1)
11 print 'matchObj.group(2)', matchObj.group(2)
12 print 'matchObj.groups()', matchObj.groups()
13 else:
14 print 'No match'
//result
# python test.py
(0, 3)
None
matchObj.group() Cats are smarter than dogs
matchObj.group(1) Cats
matchObj.group(2) smarter
matchObj.groups() ('Cats', 'smarter', 'than', 'dogs')
Finally:
做完才发现,以前也弄过,不过都是自己写代码匹配而已
但是,既然有现成的匹配模块了,为何还自己写呢?用吧,大不了自己多学点儿匹配的规则而已
肯定人家的匹配规则多多啦
