You might be able to use the RETURNING clause of the INSERT statement like this:

result = conn.execute("INSERT INTO user (name, country_id) VALUES ('Homer', 123)
                       RETURNING *")

If you only want the resulting id:

result = conn.execute("INSERT INTO user (name, country_id) VALUES ('Homer', 123)
                        RETURNING id")
[new_id] = result.fetchone()
