If I might repeat Jamie Zawinski's immortal quote:
Some people, when confronted with a problem, think "I know, I'll
use regular expressions." Now they have two problems.
If you add one section header (e.g. "[main]") to the top of the file,
you'll have a valid INI-format file which can be parsed by the
ConfigParser module --
