Does textwrap module has what you need? >>> import textwrap >>> textwrap.wrap('aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa', 78) ['aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa', 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'] >>> textwrap.wrap('This is a very long String. A linewrap module has couple functions which might help you to accoplish your goal. HTH', 78) ['This is a very long String. A linewrap module has couple functions which might', 'help you to accoplish your goal. HTH'] -- http://mail.python.org/mailman/listinfo/python-list
