Both. It's a strongly-adhered-to naming convention, as an indicator to the reader how that name should be used. foo Ordinary name, part of public interface _foo Ordinary name, part of internal-only interface __foo Ordinary name, but will be mangled (this style used rarely) __foo__ Name which is used in a special way by Python There's no change in the objects themselves; the underscores rather indicate how those names are expected to be accessed. -- \ “Pinky, are you pondering what I'm pondering?” “I think so, | `\ Brain, but Tuesday Weld isn't a complete sentence.” —_Pinky and | _o__) The Brain_ | Ben Finney -- http://mail.python.org/mailman/listinfo/python-list
