If you want make calling shell commands easy to yourself in Python use sh library.

In sh this would be:

  from sh import nc
  output = nc("-v", "192.168.1.1", "25")  # output is string of the command output

As always, installing Python libraries are recommended to do with virtualenv.

I use this to capture output from a system command, note that it will only get the last line. Modify around lastline as needed to get more:

def GetOutput(command):
    lastline = os.popen(command).readlines()
    result = lastline[0].rstrip()
    return result
