subprocess.Popen().communicate() will do it:
In [1]: import subprocess
In [7]: x=subprocess.Popen('ls', stdout=subprocess.PIPE,
stderr=subprocess.PIPE).communicate()
In [10]: print x[0]
...
If you just want stdout and stderr of the subprocess to go to stdout and
stderr of the calling process you can omit those arguments to Popen().
