New submission from Maciej Fijalkowski: This is what the current documentation says: -O Turn on basic optimizations. This changes the filename extension for compiled (bytecode) files from .pyc to .pyo. See also PYTHONOPTIMIZE. -OO Discard docstrings in addition to the -O optimizations. As far as I know, the only "optimization" that's done is removal of __debug__ sections and assert statements and has been like this for years. Maybe it should say so "-O does not do any optimizations, only removes assert statement" or so. ---------- assignee: docs@python components: Documentation messages: 182365 nosy: docs@python, fijall priority: normal severity: normal status: open title: Improve -O docs type: behavior _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue17232> _______________________________________
