Re: small problem with re.sub

Hi,
I have a html text stored as a string. Now I want to go through this string and find all 6 digit numbers and make links from them.
Im using re.sub and for some reason its not picking up the previously matched condition. Am I doing something wrong? This is what my code looks like:
htmlStr = re.sub('(?P<id>\d{6})','<a href=\"http://linky.com/(?P=id).html\">(?P=id)</a>',htmlStr)
It seems that it replaces it alright, but it replaces it literally. Am I not escaping certain characters?
Thanks again for the help.
Cheers

See the help for re.sub: "Backreferences, such as "\6", are replaced with the substring matched by group 6 in the pattern."

This should work:

htmlStr = re.sub('(?P<id>\d{6})','<a href="http://linky.com/\\1.html";>\\1</a>',htmlStr)
