I have a csv file that looks like this:
TEST 2012-05-01 00:00:00.203 ON 1 2012-05-01 00:00:11.203 OFF 0 2012-05-01 00:00:22.203 ON 1 2012-05-01 00:00
When you get the row from the csv.reader, and when you can be sure that the first element is a string, then you can use
row
csv.reader
if not row[0].startswith('TEST'): process(row)
