คำอธิบาย
ใช้ property DateTimeIndex.timetz ดึง numpy array ของ datetime.time objects **พร้อมข้อมูล timezone**
ตัวอย่างโค้ด
import pandas as pd
datetimeindex = pd.date_range('2021-10-20 02:30:50', periods=5, tz='Australia/Sydney', freq='ns')
print("DateTimeIndex...\n", datetimeindex)
print("\nThe numpy array (time part with timezone)..\n", datetimeindex.timetz)
ผลลัพธ์
DateTimeIndex...
DatetimeIndex(['2021-10-20 02:30:50+11:00', '2021-10-20 02:30:50.000000001+11:00',
'2021-10-20 02:30:50.000000002+11:00', '2021-10-20 02:30:50.000000003+11:00',
'2021-10-20 02:30:50.000000004+11:00'], dtype='datetime64[ns, Australia/Sydney]', freq='N')
The numpy array (time part with timezone)..
[datetime.time(2, 30, 50, tzinfo=)
datetime.time(2, 30, 50, tzinfo=)
datetime.time(2, 30, 50, tzinfo=)
datetime.time(2, 30, 50, tzinfo=)
datetime.time(2, 30, 50, tzinfo=)]
ความแตกต่าง .time vs .timetz
.time→datetime.time**ไม่มี** timezone info.timetz→datetime.time**มี** timezone info (tzinfo)
