Hi, welcome to the list.

Please do  not use reply to start a new thread it confuses threaded
readers and may mean you message will not be seen. Also please
supply a meaningful subject (as above) so we can decide if it
looks like something we can answer!

These will help you maximise the replies. Also, although not
relevant here, please include the full text of any error messages
and the Python version and OS you are using (2 or 3 etc).
Basically anything that helps us understand the context.

It is possible but I'll let some of the more regex literate users
tell you how :-)
