Not quite... >>> 1+2*3 7 >>> (1+2)*3 9 But other than that, I agree with your analysis for why Python should not be changed to allow: t = foo() as v if pred(v) else default_value Not everything needs to be a one liner. If you need this, do it the old- fashioned way: t = foo() if not pred(t): t = default_value -- Steven -- http://mail.python.org/mailman/listinfo/python-list
