How can I call an external program with a python script and retrieve the output and return code?

Best Solution

Look at the subprocess module: a simple example follows...

from subprocess import Popen, PIPE

process = Popen(["ls", "-la", "."], stdout=PIPE)
(output, err) = process.communicate()
exit_code = process.wait()
