Python Pandas - 返回帶有時區資訊的 python datetime.time 物件的 numpy 陣列
如需使用時區資訊返回 python datetime.time 物件的 numpy 陣列,請使用 datetimeindex.timetz 屬性。
首先,匯入所需庫 −
import pandas as pd
使用週期為 5,頻率為 us(即納秒)建立 DatetimeIndex −
datetimeindex = pd.date_range('2021-10-20 02:30:50', periods=5, tz='Australia/Sydney', freq='ns')
顯示 DateTimeIndex −
print("DateTimeIndex...\n", datetimeindex)僅返回帶有時區資訊的時間戳的時間部分 −
print("\nThe numpy array (time part with timezone)..\n",datetimeindex.timetz)
示例
程式碼如下 −
import pandas as pd
# DatetimeIndex with period 5 and frequency as us i.e. nanoseconds
# The timezone is Australia/Sydney
datetimeindex = pd.date_range('2021-10-20 02:30:50', periods=5, tz='Australia/Sydney', freq='ns')
# display DateTimeIndex
print("DateTimeIndex...\n", datetimeindex)
# Returns only the time part of Timestamp with timezone information
print("\nThe numpy array (time part with timezone)..\n",datetimeindex.timetz)輸出
將生成以下程式碼 −
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=<DstTzInfo 'Australia/Sydney' AEDT+11:00:00 DST>) datetime.time(2, 30, 50, tzinfo=<DstTzInfo 'Australia/Sydney' AEDT+11:00:00 DST>) datetime.time(2, 30, 50, tzinfo=<DstTzInfo 'Australia/Sydney' AEDT+11:00:00 DST>) datetime.time(2, 30, 50, tzinfo=<DstTzInfo 'Australia/Sydney' AEDT+11:00:00 DST>) datetime.time(2, 30, 50, tzinfo=<DstTzInfo 'Australia/Sydney' AEDT+11:00:00 DST>)]
