Hi Matt,
I also am almost a newbie (in Python) and my approach to variable
naming
follows more or less the Hungarian Type Notation Defined.
To better explain, I use one char or two (in small case) as a prefix of
the name of
the variable (starting in capital letters).
The prefix identifies the "type

Hmm... I used to be quite the fan of Python, yet not long ago I met
Ruby and fell in love almost instantly. Some of the features I like the
most:
- statement modifiers:
< "return a if
< "return a if a.value == true"
< "database.query(q) unless database.connect == error
(etc)
if a.value == True:
return a
if not database.connect == error:
database.query(q)
Trading two words for one word doesn't necessarily make the code
better.

Probably you could do this with PIL +
('abc') is not a tuple - this is an unfortunate result of using ()'s as
expression grouping *and* as tuple delimiters. To make ('abc') a
tuple, you must add an extra comma, as ('abc',).
