If you want to use start, use start /wait.

But you don't have to:

<code>
import threading
import time
import subprocess

def run_command (command):
   #
   # .call is shorthand for: start process and wait
   # CREATE_NEW_CONSOLE prevents it from getting messed
   #  up with the Python console
   #
   subprocess.call (
     [command],
     creationflags=subprocess.CREATE_NEW_CONSOLE
   )

t = threading.Thread (target=run_command, args=("cmd.exe",))
t.start ()

while t.is_alive ():
   print "alive"
   time.sleep (0.5)

print "Thread is dead"

</code>
