Sorry , Steve I didn't realize but thanks for pointing out I will take care
I was on a mobile phone and messed the quoted text

This is a good suggestion , I like the way the code is written , but what
I have failed to understand is how to translate the
possible TemporaryFailureErrors to a different exception class/type and
retry .
In my case , every command is executed using a run() function that
calls out to subprocess.Popen(). Which will return stdout, stderr,
exit_code and we would need to retry only for a specific
TemporaryFailureError .
Example : Say , If we are not able to SSH to the host , and I get
“connection refused” error I would want to retry only for this specific case
