I am probably missing something, but this works for me -
sub_proc1.py
--------------
from time import sleep
for i in range(5):
print(i)
sleep(1)
sub_proc2.py
--------------
import subprocess as sub
proc = sub.Popen(["python", "sub_proc1.py"])
x, y = proc.communicate()
Running sub_proc1 gives the obvious output - the digits 0 to 4 displayed
with delays of 1 second.
Running sub_proc2 gives exactly the same output.
This is using python 3.2.2 on Windows Server 2003.
