There might be other answers - but the easiest and IMHO best is to simply restart the interpreter. Because whatever you type in there, you could or should even (if it reaches some complexity) put in a small test script - and execute that from the interpreter at a shell prompt. The advantage is that you don't suffer from any side-effects e.g. IDLE has (no Tk mainloop for example) and avoid the problems you describe entirely. Together with a bunch of others. If you want/have to, you can drop into interpreter mode after script execution with python -i myscript.py Diez -- http://mail.python.org/mailman/listinfo/python-list
