Standard Python library module linecache, which others suggested, is
your best bet.  itertools.islice(open('filename'), 12, 13).next() should
also work (after an 'import itertools' of course, since it, too, is a
module in the standard library) and might be faster if you'll never need
to get any other line from that file in the course of your program.
