You should check out the csv module here: http://docs.python.org/2/library/csv.html#module-csv It will read your csv file into a list (the file rows) of lists (the columns). You can easily loop over the data to extract the columns you want using list indexing -- Joel Goldstick http://joelgoldstick.com
