Hi Richard,
I would recommend asking the PyGame folks on this one. What you're
running into is specific to that external library, and folks who work
with PyGame have encountered the problem before: they'll know how to
diagnose and correct it. For example:

As Bob prescribed, I added (and made sure to indent):

The fourth printed line appears to be the same:

This is consistent with what I observe as the first three age observations

The reason is that raw_input() returns a string. What you are trying

OK, so it looks like you're not matching.
Remember match only matches at the start of a line, so try re.search instead.
