I knew you could do

for item in dictionary:

instead of

for item in dictionary.keys():

But I didn't realise it worked for a single item test too

if item in dictionary

instead of

if dictionary.has_key(item):

While the loop is probably as easy to read either way
the test is much cleaner using 'in'.

Nice.
