python例子三

例一：匹配长度为1-15的域名

#-*-encoding:utf--*-
import re

regex=re.compile('^www[.][a-z]{1,15}[.](com|org)')
m1=re.match(regex, 'www.baidu.com')
#m2=re.match(regex, 'abcdefghig')

if m1 is not None:
    print 'true1'
#if m2 is not None:
 #   print 'true2'

例二：匹配010 022之类的电话号码

#-*-encoding:utf--*-
import re

regex = re.compile('\(?0\d{2}[)-]?\d{8}')

m1= re.search(regex, '(010)8886666')
m2=re.search(regex, '022-22334455')
m3=re.search(regex, '')
m4= re.search(regex, '(010)88886666 022-22334455 02912345678')

if m4 is not None:
    print m4.group()
m5 = re.findall(regex,'(010)88886666 022-2233s4455 02912345678')
print m5
