How do I capture the output of os.system()

[Frank Teoh]

I am trying to capture the output of os.system() into a string without
success. Since os.system() returns only its exit_status, how can I do
that?
system(...)
system(command) -> exit_status

Execute the command (a string) in a subshell.

My aim is to capture the return value of os.system("rsh
<netapp_filer_host> qtree")

Thanks.

You should better use os.popen. Please see the documentation of popen in
the os module:
