"Always produce the same output?" Well, hardly, as even a token test proves: >>> a = 'testing\'this' >>> print '%r' % a "testing'this" >>> b = r'testing\'this' >>> print "'%s'" % b 'testing\'this' Do you realize that '%r' % a just outputs whatever repr(a) returns? And that '%s' % a just outputs whatever str(a) returns? -Peter -- http://mail.python.org/mailman/listinfo/python-list
