Python 2.4 makes the fieldnames paramter optional:
   "If the fieldnames parameter is omitted, the values in the first row of the 
csvfile will be used as the fieldnames."

i.e. the following should work fine in 2.4:

for row in csv.DictReader(file(filename)):
   print sorted(row.items())

Cheers,
Nick.
