Can you explicitly make the child inherit parent's streams?

from sys import stdout, stderr
from subprocess import Popen
Popen(['ls'], shell=True, stdout=stdout, stderr=stderr)

As a workaround, you can also do stdout=PIPE and stderr=PIPE and then
print out the contents of Popen's stdout and stderr stream properties.
HTH,

Sergey.
