yeah thanks!

i translated as:

....
import os
....
CMD_STDIN, CMD_STDOUT, CMD_STDERR = \
   os.popen3("*some_system_command*", "r")
if not CMD_STDERR.readlines():
   ...
   *do_something*
   ...
   for answer in CMD_STDOUT:
     print answer,
   ...
   *do_something_more*
   ...
else:
   ...
   *do_something_else*
   ...
CMD_STDIN.close()
CMD_STDOUT.close()
CMD_STDERR.close()
....

bye
