I might also suggest that you consider using ConfigParser module to store
your "variables".  If you are worried about performance, I can tell you that
I use it to feed thousands of lines of configuration info into one of my
applications (this app has 5 of these files) and ConfigParser handles them
so quickly that performance is NOT a problem.  The format of the file is
easily understandable by nearly every user which means I don't have to
worry with someone not understanding Python's syntax.  If someone gets
something wrong in a file that gets included, it is harder to take a sane
default or handle the error than with ConfigParser.  Just a suggestion that
I hope helps.
