问题
Sometime I'd like to spawn a child process with the same optimization flags used to start the parent.
I can use something like:
optimize = not __debug__
But this way I match both -O and -OO flags.
Is there some python internal status that contains that info?
回答1:
After some digging in the documentation I've found that the sys.flags struct sequence (http://docs.python.org/dev/library/sys#sys.flags) that has an optimize attribute containing the information I was searching for.
python -c "import sys; print sys.flags.optimize" -> 0
python -O -c "import sys; print sys.flags.optimize" -> 1
python -OO -c "import sys; print sys.flags.optimize" -> 2
