And still better improved with while ans[:1].lower() != 'y': ans = input('Do you like python?') in the event that len(ans)==0 (a situation which will crash the various current examples). It also only expends the effort to lowercase 0-or-1 characters, rather than lowercasing an entire string just to throw away everything except the first character. -tkc -- https://mail.python.org/mailman/listinfo/python-list
