How to call an external program in python and retrieve the output and return code?

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

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()
