octoshape:rthk.ch6 香港电台普通话台
octoshape:rthk.ch3 香港电台第三台(英)
what i want to get the result is
1group is http://202.177.192.119/radio5 2group is 香港电台第五台 3group is (可于Totem/VLC/MPlayer播放)
1group is http://202.177.192.119/radio35 2group is 香港电台第五台 3group is (DAB版，可于Totem/VLC/MPlayer播放)
1group is http://202.177.192.119/radiopth 2group is 香港电台普通话台 3group is (可于Totem/VLC/MPlayer播放)
1group is http://202.177.192.119/radio31 2group is 香港电台普通话台 3group is (DAB版，可于Totem/VLC/MPlayer播放)
1group is octoshape:rthk.ch1 2group is 香港电台第一台 3group is (粤)
1group is octoshape:rthk.ch2 2group is 香港电台第二台 3group is (粤)
1group is octoshape:rthk.ch6 2group is 香港电台普通话台 3group is none
1group is octoshape:rthk.ch3 2group is 香港电台第三台 3group is (英)
here is my code:
# -*- coding: utf-8 -*-
import re
rfile=open("tv.txt","r")
pat='([a-z].+?\s)(.+)(\(.+\))'
for line in rfile.readlines():
Match=re.match(pat,line)
print "1group is ",Match.group(1),"2group is ",Match.group(2),"3group is ",Match.group(3)
rfile.close()
the output is :
1group is http://202.177.192.119/radio5 2group is 香港电台第五台 3group is (可于Totem/VLC/MPlayer播放)
1group is http://202.177.192.119/radio35 2group is 香港电台第五台 3group is (DAB版，可于Totem/VLC/MPlayer播放)
1group is http://202.177.192.119/radiopth 2group is 香港电台普通话台 3group is (可于Totem/VLC/MPlayer播放)
1group is http://202.177.192.119/radio31 2group is 香港电台普通话台 3group is (DAB版，可于Totem/VLC/MPlayer播放)
1group is octoshape:rthk.ch1 2group is 香港电台第一台 3group is (粤)
1group is octoshape:rthk.ch2 2group is 香港电台第二台 3group is (粤)
1group is
Traceback (most recent call last):
File "tv.py", line 7, in <module>
print "1group is ",Match.group(1),"2group is ",Match.group(2),"3group is ",Match.group(3)
AttributeError: 'NoneType' object has no attribute 'group'
how to revise my code to get the output?
