You're coming from a Perl background, right? No-one else would
think of using a regexp for such a simple thing. There are two
things you need to learn:
(a) Python doesn't do automatic variable interpolation in strings.
(b) For simple find and replace operations, there are string
methods which are easier and faster than regexps.
