>>> csv.reader(["Pie=peach,quantity=2,ingredients='peaches,powdered sugar'"], quotechar = "'").next() ['Pie=peach', 'quantity=2', "ingredients='peaches", "powdered sugar'"] i.e., it doesn't allow separators within fields unless either the *whole* field is quoted: >>> csv.reader(["Pie=peach,quantity=2,'ingredients=peaches,powdered sugar'"], quotechar = "'").next() ['Pie=peach', 'quantity=2', 'ingredients=peaches,powdered sugar'] >>> or the separator is escaped: >>> csv.reader(["Pie=peach,quantity=2,ingredients='peaches\,powdered sugar'"], quotechar = "'", escapechar = "\\").next() ['Pie=peach', 'quantity=2', "ingredients='peaches,powdered sugar'"] >>> Michael -- http://mail.python.org/mailman/listinfo/python-list
