Normally you would use eval(..) however this is considered by many to be evil and bad practise (especially by me!) I would advise you use pickle instead. Using eval (evil): >>> li = [1, 2, 3] >>> s = repr(li) >>> s '[1, 2, 3]' >>> lii = eval(s) >>> lii [1, 2, 3] >>> lii == li True Using pickle (better): >>> from pickle import dumps, loads >>> li = [1, 2, 3] >>> s = dumps(li) >>> s '(lp0\nI1\naI2\naI3\na.' >>> lii = loads(s) >>> lii [1, 2, 3] >>> lii == li True cheers James -- http://mail.python.org/mailman/listinfo/python-list
