You can upgrade to the latest release with:

Developmental releases¶
New versions of unihan-db are published to PyPI as alpha, beta, or release candidates. In their
versions you will see notification like a1, b1, and rc1, respectively. 1.10.0b4 would mean
the 4th beta release of 1.10.0 before general availability.

#!/usr/bin/env python

import logging
import pprint
import typing as t
from sqlalchemy.sql.expression import func
from unihan_db import bootstrap
from unihan_db.tables import Unhn
log = logging.getLogger(__name__)
logging.basicConfig(level=logging.INFO, format="%(message)s")
def run(unihan_options: t.Optional[t.Dict[str, object]] = None) -> None:
"""Initialize Unihan DB via ``bootstrap_unihan()``."""
session = bootstrap.get_session()
bootstrap.bootstrap_unihan(session)
random_row_query = session.query(Unhn).order_by(func.random()).limit(1)
assert random_row_query is not None
random_row = random_row_query.first()
log.info(pprint.pformat(bootstrap.to_dict(random_row)))
assert random_row is not None
log.info(pprint.pformat(random_row.to_dict())) # type:ignore
if __name__ == "__main__":
run()
