Revision 2. </p> <p>If you aren't very careful, modules can end up exporting more symbols than you intend. For example, everything that you import is added to your module's name-space. Then there's scaffolding and other stuff intended for internal use. The usual advice is to name everything with a leading underscore, but that gets complicated fast: "import sys as _sys", "from os import environ as _environ". The alternative is to use "__all__ " to define exactly what you want to export, but then you need to maintain it as you add things to your module. <em>Or do you?</em></p>
