Right. I didn't understand why ‘__file__’ is a suitable substitute for ‘sys.executable’; they're always (?) different values. So that probably is what led to the confusion in the code behaviour. I hope the Pythonic idioms are helpful to the original poster nevertheless. -- \ “Anyone who believes exponential growth can go on forever in a | `\ finite world is either a madman or an economist.” —Kenneth | _o__) Boulding | Ben Finney -- https://mail.python.org/mailman/listinfo/python-list
