I have to process a csv file from a business partner. Oddly (?) they don't quote text fields, and the Title field sometimes contains commas. So I wrote some code to count the commas in each line and if there were too many, I removed the extras and wrote the cleaned up file to the original filename for the rest of what I have to with that data -- Joel Goldstick _______________________________________________ Tutor maillist - [email protected] To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
