Better way to isolate string

HMS Surprise

Greetings.

Given the string s below and using only python built-in capabilities,
I am trying to isolate the substring G132153. This string may have any
number of digits but the pieces around it will not change. I have
accomplished this with split but there must be a more elegant and
compact way to do this.

>>s ='<a href="../active/Group_Detail.php?GroupID=G132153&SvcType=1&AType=V " class="dvLink">G132153</a>'
t = s.split('">')
u = t[-1].split('<')
v = u[0]
v

'G132153'
Thanks,

jvh

I suppose a one liner would look better, but I am alway leery of these
things 'breaking'.

t = s.split('">')[-1].split('<')[0]
s ='<a href="../active/Group_Detail.php?
GroupID=G132153&SvcType=1&AType=V" class="dvLink">G132153</a>'

Only if you're competing in an obscurity competition ;)

If you're really confined to built-ins (ie you can't import
a single module) then just go with your original solution.
Why not?

If you can import modules, then you want to look
at the urlparser and cgi modules, I suspect.
