How do I suppress "Cmd exec error."

How do I suppress "Cmd exec error."

import paramiko

# ...

cli_x = "something unknown"
ssh_client = paramiko.SSHClient()
stdin, stdout, stderr = ssh_client.exec_command(cli_x)

I'm having a hard time finding documentation on these generated messages, which are NOT part of stdout, or stderr. All I want to do is suppress the output.

Output:
Syntax error while parsing 'something unknown'
Cmd exec error.

Thanks
x

Is there no Python exception traceback?
