And these will give two different results. The QBasic version says "ad.txt" "ad.csv" whereas the python version will give "ad.txt" "ad.txt.csv" so you need to say infile = sys.argv[1] outfile = sys.argv[1][:-3]+'csv' or something equivalent. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
