从运行的python脚本中检测optimize标志是否为-O或-OO [英] Detect from a running python script if the optimize flag is -O or -OO

问题描述

有时候我想产生一个具有与启动父进程相同的优化标志的子进程.

Sometime I'd like to spawn a child process with the same optimization flags used to start the parent.

我可以使用类似的东西:

I can use something like:

optimize = not __debug__

但是通过这种方式，我同时匹配了-O和-OO标志.

But this way I match both -O and -OO flags.

是否存在一些包含该信息的python内部状态?

Is there some python internal status that contains that info?

推荐答案

在对文档进行一些挖掘之后，我发现sys.flags结构序列(

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
