Create the following on cumin1001:

razzi@cumin1001:~$ cat spicerack_repl.py
#!/usr/bin/env python3
from spicerack import Spicerack

spicerack = Spicerack(dry_run=False)

remote = spicerack.remote()

section = 's3'

query = f"A:db-wikireplica and A:db-section-{section} and not A:wikireplicas-dedicated"

wikireplicas = remote.query(query)

Run it like so:

sudo python3 -i spicerack_repl.py

Then you can, for example, find how to access a command's stdout interactively:

razzi@cumin1001:~$ sudo python3 -i spicerack_repl.py
>>> remote_host.run_sync('echo 3')
----- OUTPUT of 'echo 3' -----
3
