Now how do i get link of rss or atom feed for each user ?? i dont want to use regular expressions...

Note - the atom feed link for each user(eg Shapado http://identi.ca/user/77141) looks like this - http://identi.ca/api/statuses/user_timeline/77141.atom

I think i will use an old python function split() to break the url and get the uid..

print c
n=c[1].split('/')
print n[4]

And the op is

u'57601'
