How to find all Pleiades URIs that correspond to a Trismegistos place URI

findit.py

# read in the json and get the graph of places
import json
with open('pleiades-places-latest.json', 'r', encoding='utf-8') as f:
    pj = json.load(f)
graph = pj['@graph']

# iterate through the graph and test each place for a TM reference
for place in graph:
    references = place['references']
    tm_geoids = [r['accessURI'] for r in references if 'trismegistos' in r['accessURI']]
    if len(tm_geoids) == 1:
        print('{} = {}'.format(place['uri'], tm_geoids[0]))

Thanks @fosco13! I've updated the gist.
