Used like this, for executing jar files:

output = exec_cmd("java -jar SomeJarFile.jar")

Learned, in this thread [1], that I can do:

import subprocess as sub

output = sub.check_output("java -jar SomeJarFile.jar")

... or (if using http://amoffat.github.io/sh/):

import sh
output = sh.java("-jar", "SomeJarFile.jar")

Nice!
