R. David Murray <rdmur...@bitdance.com> added the comment: I was definitely wrong about the "obvious" part, then. The 'if __debug__:' idiom is completely optimized away by -O, just like asserts are. That is, in -O mode, there is no if test, the code block is just omitted entirely.
Having said that, though, I can't find it documented other than by the implicit equivalence given in the assert docs. Hmm. Yes, it does seem to be a CPython implementation detail. See issue 8379. Assert being removed is also an implementation detail, though (see the reference to "the current code generator..." in the assert docs). I suppose that '-O' itself is a CPython implementation detail, in a sense :) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14868> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
