how to match a url in urls.py

Hello,

I want to match a url in urls.py. Can you teach me how to do it? Thanks.I have tried the following two versions. But as long as I put a . (dot) in the regular expression, it gives me a "bad character range" error.

   (r'^pagerank/(?P<url>([/w-]+/.)+[/w-]+.([^a-z])(/[/w-: ./?%&=]*)?|[a-zA-Z/-/.][/w-]+.([^a-z])(/[/w-: ./?%&=]*)?)', 'ueseo.pagerank.views.CheckPageRankStatic'),# a static page version of page rank check
  
   (r'^pagerank/(?P<url>[a-zA-Z0-9_-.]+))', 'ueseo.pagerank.views.CheckPageRankStatic'),# a static page version of page rank check
