Pass CREATE_NEW_CONSOLE as one of the creationflags:

import os, sys
import subprocess

processes = []
cmd = [sys.executable, "-c", "import os; print os.getpid (); raw_input ()"]
for i in range (3):
   processes.append (subprocess.Popen (cmd, 

# Keep looping round to see the current status
while True:
   for p in processes:
     print p.poll ()

   raw_input ()
