I'm not sure about this code, as or is a Boolean operator... Wouldn't maps.get(KEY, {}).get('uuid', FALLBACK_UUID) be better?

MALE_UUID = (
    maps.get(('NCBITaxon:9606', 'PATO:0000384'), {}).get('uuid')
    or "2b76d336-5c56-55e3-ab1e-795d6c63f9c1"
)
FEMALE_UUID = (
    maps.get(('NCBITaxon:9606', 'PATO:0000383'), {}).get('uuid')
    or "91359a0f-9e32-5309-b365-145d9956817d"
)
RAT_UUID = (
    maps.get(('NCBITaxon:10114', None), {}).get('uuid')
    or "fb6d0345-cb70-5c7e-893c-d744a6313c95"
)

Thanks for the suggestion. I initially used or to handle the case where uuid might be None.
However, because the service guarantees uuid will always be present, your .get(..., FALLBACK_UUID) approach is cleaner and I’ve applied the change.

The recommended test for None is to use is None and not assume a false value. Regardless, although None or 'value' will evaluate to 'value', it's confusing to see a Boolean valued result being assumed to be a string...
