Avamar and python

I have two questions:

One: Is there a way to create a python script for Avamar to use the snapups command? At the moment I'm having to rdp into each server and run a command (ddbmexptool -k -v -n mssql -Y -z "C:\ddbconfig.cfg") to delete expired backups. I'm looking for a way to do this without having to rdp into each server and putty into Avamar to run the snapups command. 

Two: I have a python script to validate restores, but I'm getting an error saying "FileNotFoundError: [WinError 2] The system cannot find the file specified" for this command

cmd = subprocess.Popen(['/usr/local/avamar/bin/mccli','client', 'show', '--recursive=true'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)

(out, err) = cmd.communicate()

if cmd.returncode == 0:
    os.system('cls')
    print ("Command ran.")
    list = out.split('\n')
    list = list[3:]
    formatList(list)
else:
    print ("Issue with command")
    print (out, err)

I'm running this from a Win 10 box to communicate with Avamar. I didn't create this script, I'm trying to fix it. The programmer who created it is no longer with the company.
