I think this is the case which calls for the distinction: >>> str(["1", "2", "3"]) "['1', '2', '3']" >>> str([1, 2, 3]) '[1, 2, 3]' If the first case did as you suggested you couldn't distinguish it from the second. Look at this -- it seems to me that it should work fine.... ---- Python 2.5.1 (r251:54863, Apr 15 2008, 22:57:26)

str("qwer") 'qwer' repr("qwer") "'qwer'"
