This example is broken; here's what you get when you run it: >>> def f(wrappedParam): ... wrappedParam[0] += 5 ... return "this is my result" ... >>> # call it ... x = 2 >>> result = f([x]) >>> x 2 You probably intended something more like: >>> x = [2] >>> result = f(x) >>> x[0] 7 (As for the actual topic, I'm personally -0 for adding in-out parameters to python.) -Edward _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
