Given a transaction, how do I get a list of all of the transactions that reference it as their trunk or branch? I'm using pyota, but solutions in the other libraries would be appreciated too.

There is the findTransactions api (with the approvees parameter) that return the list of all transactions directly approving the one (or the multiple) passed in parameter :

curl <NODE_URL> \
  -X POST \
  -H 'Content-Type: application/json' \
  -H 'X-IOTA-API-Version: 1' \
  -d '{"command": "findTransactions", "approvees":"<TX_HASH>"]}'
