import osThe os.popen() will treat the output (stdout, stderr) as file object, so you can capture the output of the external programs. It is one of the synchronous methods.
print os.popen("echo Hello, World!").read()
import osBy acting like double-click in the file explorer, you can use os.startfile() to launch external program that is associated with this file. This is an asynchronous method.
import osIt will throw out an exception if file is not found.
import win32apiOf course, this is only available on windows platforms. The subprocess package provides a syncrhonous and an asynchronous methods: namely, call and Popen. Both methods take the first parameter as a list. For example,
import subprocessYou can use wait() to synchronous the processes.
# thread continues ...
import subprocessAnother asynchronous method would be to use asynproc package. The example is given below.
p = subprocess.Popen('ls', shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
for line in p.stdout.readlines():
retval = p.wait()
import osThe following is a popular script taken from stackoverflow which shows the usage of subprocess package.
from asynproc import Process
myProc = Process("notepad.exe")
# check to see if process has ended
poll = myProc.wait(os.WNOHANG)
if poll != None:
# print any new output
out = myProc.read()
if out != "":
from subprocess import Popen, PIPE
running_procs = [
Popen(['/usr/bin/my_cmd', '-i %s' % path], stdout=PIPE, stderr=PIPE)
for path in '/tmp/file0 /tmp/file1 /tmp/file2'.split()]
for proc in running_procs:
retcode = proc.poll()
if retcode is not None: # Process finished.
else: # No process is done, wait a bit and check again.
# Here, `proc` has finished with return code `retcode`
if retcode != 0:
