Any idea how I can fix this ? I am ok to use any other re method(not > only tied to re.search) as long as it works. Hi again Pradeep, We are now on email number seven, so I am going to try to give you some good advice ... When you ask on a forum like this for help, it is very important to show people exactly what you did. Everything that you did. In the shortest possible way that demonstrates whatever issue you are facing. It is best to give us a recipe that we can follow exactly that shows every step that you do when you have the problem that you need help with. And the best way to do that is for you to learn how to cut and paste between where you run your problem code, and where you send your email message to us. Please observe the way that I communicated with you last time. I sent you an exact cut and paste from my terminal, to help you by allowing you to duplicate exactly every step that I made. You should communicate with us in the same way. Because when you write something like your most recent message > I got the error after matches.group(0) as follows: > AttributeError: NoneType object has no attribute 'group'. this tells us nothing useful!! Because we cannot see everything you did leading up to that, so we cannot reproduce your problem. For us to help you, you need to show all the steps, the same way I did. Now, to help you, I found the same old version of Python 2 that you have, to prove to you that it works on your version. So you talking about updating Python is not going to help. Instead, you need to work out what you are doing that is causing your problem. Again, I cut and paste my whole session to show you, see below. Notice that the top lines show that it is the same version that you have. If you cut and paste my commands into your Python then it should work the same way for you too. If it does not work for you, then SHOW US THE WHOLE SESSION, EVERY STEP, so that we can reproduce your problem. Run your python in a terminal, and copy and paste the output you get into your message. $ python Python 2.7.3 (default, Jun 20 2016, 16:18:47) [GCC 4.7.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import re >>> mystr = "where is my-dog" >>> pattern = re.compile(r'my-dog$') >>> matches = re.search(pattern, mystr) >>> matches.group(0) 'my-dog' >>> I hope you realise that the re module has been used by thousands of programmers, for many years. So it's extremely unlikely that it "doesn't work" in a way that gets discovered by someone who hardly knows how to use it. -- https://mail.python.org/mailman/listinfo/python-list
