using rescepy for scripting

I would like to use rescepy as part of a script

for example if it was successful, all files ok, none missing, then i would like to run another command, like compress the folder

000-eminem-the_marshall_mathers_lp-repack-cd-flac-2000.sfv: 18 files, 18 OK, 18 misnamed. 10.650 seconds, 42971.4K/s

if there is an error like below

Searching on srrdb.com … 1c

Errors: 1

I would want to do nothing further

Also the same if there are files missing

00-cecil_taylor—for_olim-1987-oma.sfv: 8 files, 7 OK, 1 not found. 0.121 seconds, 297037.0K/s

Errors: 1

i want to stop further processing.

Any ideas how I could do this?

Thanks in advance
