subprocess.call requiring all parameters to be separated by commas

Question

I used to be able to do a subprocess.call([\"command\",\"-option value -option value\"]) and it would work there was a change to the command to work properly

Answer 1

You'll need to specify shell=True to get subprocess.call to interpret the string.

See the note in the subprocess.Popen constructor documentation (the subprocess.call method takes the same arguments as the subprocess.Popen constructor).

Answer 2

Avoid shell=True if you can -- it's a security risk. For this purpose, shlex.split suffices:

import subprocess
import shlex
subprocess.call(shlex.split("command -option value -option value"))
