DocNow/twarc:

v2.7.0 adds a new places command to search for places and their identifiers, which can be used in search and stream queries. Even though it's still on the 1.1 endpoint the 1.1/geo/search.json API endpoint makes these place identifiers available when searching by the name, geo coordinates, or ip address.

Usage: twarc2 places [OPTIONS] VALUE [OUTFILE]

  Search for places by place name, geo coordinates or ip address.

Options:
  --type [geo|name|ip]            How to search for places
  --granularity [neighborhood|city|admin|country]
                                  What type of places to search for
  --max-results INTEGER           Maximum results to return
  --json                          Output raw JSON response
  --help                          Show this message and exit.

There is a corresponding method twarc.client2.Twarc2.geo() method which you can use to do the lookup yourself from Python.
