Matty, %r in a format string is very much like %s.  %s calls str(your_object) in order to produce the resulting string.  %r calls repr(your_object).  Generally, you'd want to use %s for strings that will surface to a user, while %r is great for debugging and logging.

Also, if you haven't come across repr(), you should be able to find that in the docs; it's also considered good practice to overload repr() in your own classes in order to provide a useful representation for your objects.
