I presume you're suitably sanitizing $value before you arbitrarily use it ;-)?

Not sure what you're trying to do, here, with the extra regex groups? If you
just want to naively check for the presence of that user-input value, you can
do:
seek = sanitize(form["serial"].value)
for line in file:
match = re.search(seek, line) # re.search(pattern, string, flags)
if match is not None:
print "%s matches" % line
One thing that certainly confused me when I learned Python (coming from, among
other things, Perl) was the lack of implicit variables -- is that what's
tripping you up?
Hope that helps,
Rami
