Thanks everyone for your help. I got Skip's answer to work (mine is
pasted below):
import sys
import csv
last = {}
reader = csv.DictReader(open("/home/mwaite/test/test2.csv", "rb"))
writer = csv.DictWriter(open("/home/mwaite/test/test3.csv", "wb"),
['ZONE','CITY','EVENT'], dialect='excel')
for row in reader:
for key in row:
if not row[key]:
row[key] = last.get(key, "")
writer.writerow(row)
last = row
