You can use the CSV module to read in your CSV file and write out an edited version with an appended column. Remember that adding a column is adding an extra entry to the end of each line.

An example of outputting with the CSV module (http://docs.python.org/library/csv.html)

>>> import csv
>>> spamWriter = csv.writer(open('eggs.csv', 'wb'), delimiter=' ',
...                         quotechar='|', quoting=csv.QUOTE_MINIMAL)
>>> spamWriter.writerow(['Spam'] * 5 + ['Baked Beans'])
>>> spamWriter.writerow(['Spam', 'Lovely Spam', 'Wonderful Spam'])
