ouput redirection..a newbie question

[Lonnie Princehouse]

You can also use os.popen() to capture the output of a shell command:

import os
p = os.popen('ls -al')
output = p.read()  # read output of command
print output


(a variation on this, os.popen3, can be used if you need to capture
stdout and stderr separately...)
