But function calls with side effects _do_ have a defined order of evaluation. Left to right. And the answer should be 4. http://docs.python.org/reference/expressions.html#evaluation-order >>> def set_(d, k, v): ... d[k] = v ... return v ... >>> d = {} >>> set_(d, 'x', 1) 1 >>> set_(d, 'y', set_(d, 'x', 2) + d['x']) 4 -- Devin -- http://mail.python.org/mailman/listinfo/python-list
