防止python multiprocess进程访问stdout

Question

I have a script that is calling an external library in a child process, this external library is printing status updates in the from of sys.stdout.write calls.

Its interface has no option for suppressing them, is there any way to redirect a child process' stdout to hide it?

The program is using multiprocessing.Process the code snippet would be slightly unweildy as the call to stdout.write happens a few classes deep inside a generator.

sys.stdout = open(os.devnull)
