Thanks all ! > Question: what if two values are equidistant?
>>> def closest(foo,v): ... intermed = [(abs(v), v) for v in foo] ... intermed.sort() ... return [x[1] for x in intermed if x[0] == intermed[0][0]] ... >>> print closest([-20,-10,10,15],0) [-10, 10] Works fine ! (now with sorted ... ?) -- http://mail.python.org/mailman/listinfo/python-list
