I recommend "The Pragmatic Programmer," (Hunt, Thomas) ISBN
978-0201616224 and "The Practice of Programming," (Kernighan,
Pike) ISBN 978-0201615869 for more practical tips like this one.
As a mostly self-taught programmer, both books helped me
immensely. If you're a seasoned pro with a CS degree, you might
not find them quite as interesting, though. The second book,
especially, does not cover issues relating to large scale
software development.

As for factoring out re.compile, I believe they are cached by the
re module, so you would save the cost of retrieving the cached
regex, but not the cost of building it.
