Jim, once you've got the values to be separated into an array, you
can use string.join to put commas between them. Does that help?

--- csv.py ---
import string

def csv(filename):
    lines = open(filename).readlines()
    for line in lines:
        fields = string.split(line)
        print string.join(fields, ',')

csv('csv.py')
