First, note that form["date"] is all you need. form["date"].value is redundant.
I would do this with sets: import string if set(form["date"]) & set(string.ascii_letters) != set([]): print "You have to enter a date with numbers" if set(form["purchases"]) & set(string.digits) != set([]): print "Please do not use numbers" Sets take time to construct, but they test membership faster than strings. Plus, the code just reads logically. (The &, if you couldn't figure it out, does an intersection of sets. You could also use the .intersection method for even better readability). -- http://mail.python.org/mailman/listinfo/python-list
