Python Pandas – 将 DateTimeIndex 转换为 Series
要将 DateTimeIndex 转换为 Series,请使用 DateTimeIndex.to_series() 方法。
首先,导入所需的库−
import pandas as pd
创建将要使用的 DateTimeIndex,周期为 5,频率为 S,即秒。时区为澳大利亚/阿德莱德−
datetimeindex = pd.date_range('2021-10-18 07:20:32.261811624', periods=5,
tz='Australia/Adelaide', freq='40S')
将 DateTimeIndex 转换为 Series−
print("\nDateTimeIndex to series...\n",
datetimeindex.to_series())
示例
以下是代码−
import pandas as pd
# DatetimeIndex with period 5 and frequency as S i.e. seconds
# timezone is Australia/Adelaide
datetimeindex = pd.date_range('2021-10-18 07:20:32.261811624', periods=5,
tz='Australia/Adelaide', freq='40S')
# display DateTimeIndex
print("DateTimeIndex...\n", datetimeindex)
# display DateTimeIndex frequency
print("DateTimeIndex frequency...\n", datetimeindex.freq)
# Convert DateTimeIndex to Series
print("\nDateTimeIndex to series...\n",
datetimeindex.to_series())
输出
这将产生以下代码−
DateTimeIndex...
DatetimeIndex(['2021-10-18 07:20:32.261811624+10:30',
'2021-10-18 07:21:12.261811624+10:30',
'2021-10-18 07:21:52.261811624+10:30',
'2021-10-18 07:22:32.261811624+10:30',
'2021-10-18 07:23:12.261811624+10:30'],
dtype='datetime64[ns, Australia/Adelaide]', freq='40S')
