Newbie backreference question
Hi, In perl I can do something like: $a = 'test string'; $a =~ /test (\w+)/; $b = $1; print $b . "\n"; and my output would be "string". How might this snippet be written in python? Thanks to all... -- http://mail.python.org/mailman/listinfo/python-list

No, sorry - my bad. I am looking to assign the
backreference to another variable so it can be treated
seperately. So perhaps:
$a = 'test string two';
$a =~ /test \w{2}([\W\w]+)/;
$b = $1;
print $b . "\n";
producing "ring two".
I have read the docs and faqs but remain too dense
to comprehend.
Thanks again...

Of course, this is the answer I need. I've been futzing
around with \1 and such without much luck. I'm still thinking a
bit too perlishly. :)
Thanks again, all!
