Blank rows resulting from simple csv script

[Drew]

Hi all -

I've written a simple script to read a .csv file and then write out
rows to a new file only if the value in the 4th column is a 0. Here's
the code:

import csv

reader = csv.reader(open('table_export.csv','rb'))

writer = csv.writer(open('new_jazz.csv','w'))

for row in reader:
if row[3] == '0':
writer.writerow(row)

This is writing out the correct rows, however it is writing a blank
row between each of the rows written out. Any ideas?

Thanks,
Drew

The modes aren't compatible - either use rb, wb or r,w

Bzzzzt! *ALWAYS* use binary mode for both reading and writing.
