Yep, that's the one I was using:

# Get a list of existing snapshots using zfs list
# All snapshots starting with data/db are potentially eligible for culling
print "Enumerating snapshots..."
cull_list=[ (s.split()[0],mkdate(s.split()[0])) for s in
                    subprocess.check_output(["zfs", "list", "-r", "-t",
"snapshot", ]).splitlines()
                        if s.startswith("data/db") ]
