対応パターン例
datetimeの変換
dt = to_datetime("2024年4月5日22時30分4秒")
self.assertEqual(dt, datetime(year=2024, month=4, day=5, hour=22, minute=30, second=4))
dt = to_datetime("2020年5月7日")
self.assertEqual(dt, datetime(year=2020, month=5, day=7))
dt = to_datetime("二〇二五年十二月七日")
self.assertEqual(dt, datetime(year=2025, month=12, day=7))
dt = to_datetime("二千年八月三日")
self.assertEqual(dt, datetime(year=2000, month=8, day=3))
dt = to_datetime("弐零弐参年伍月肆日")
self.assertEqual(dt, datetime(year=2023, month=5, day=4))
timedeltaの変換
td = to_timedelta("二時間三十秒")
self.assertEqual(td, timedelta(hours=2, seconds=30))
td = to_timedelta("六日間二時間五分間三秒間")
self.assertEqual(td, timedelta(days=6, hours=2, minutes=5, seconds=3))
td = to_timedelta("六日二時五分三秒")
self.assertEqual(td, timedelta(days=6, hours=2, minutes=5, seconds=3))
td = to_timedelta("90秒")
self.assertEqual(td, timedelta(seconds=90))
td = to_timedelta("マイナス七億分")
self.assertEqual(td, timedelta(minutes=-700_000_000))
