I will do my best : I guess that you are about to write your own non python interpreter (I mean, it will interpret some language that is not Python) and your interpreter sadly writes "None" when there is none to write. Is that correct ? If yes, I suggest that you replace somewhere in your code: print result by if result is not None: print result I know that this is not the question but if it is right that your interpreter is not a python interpreter and that you build a console on top of it (I know many assumptions, ...), I would like to kindly suggest you to use something else that the Python prompt (">>>") - at least on this NG - I am afraid that _this_ didn't help anybody to understand what you meant. If by pure coincidence, this helped you, it would unexpectingly enlight my day ... and please don't tell me that my english is perfect, I know it perfectly well. -- http://mail.python.org/mailman/listinfo/python-list
