It's in the documentation:

os module:
  system (command)
      Execute the command (a string) in a subshell. This is implemented by
      calling the Standard C function system(), and has the same limitations.
      Changes to posix.environ, sys.stdin etc. are not reflected in the
      environment of the executed command. The return value is the exit status
      of the process encoded in the format specified for wait().

I don't know how to get the output on DOS systems: os.pipe() and sisters are
not available on your platform, but this may be well enough.

regards,
Gerrit.
