Python Pandas - 如何以秒频率舍入 TimeDeltaIndex

要以秒频率舍入TimeDeltaIndex，请使用方法。对于秒频率，使用值为S的freq参数。TimeDeltaIndex.round()

首先，导入所需的库-

import pandas as pd

创建一个TimeDeltaIndex对象。我们已经使用data参数设置了类似timedelta的数据-

tdIndex = pd.TimedeltaIndex(data =[10 day 5h 2 min 3us 10ns, +22:39:19.999999, 2 day 4h 03:08:02.000045, +21:15:45.999999])

显示TimedeltaIndex-

print("TimedeltaIndex...\n", tdIndex)

以秒频率对TimeDeltaIndex日期进行舍入操作。对于秒频率，我们使用了“S”-

print("\nPerforming round operation with seconds frequency...\n", tdIndex.round(freq=S))

示例

以下是代码-

import pandas as pd #CreateaTimeDeltaIndexobject # We have set the timedelta-like data using the data parameter tdIndex = pd.TimedeltaIndex(data =[10 day 5h 2 min 3us 10ns, +22:39:19.999999, 2 day 4h 03:08:02.000045, +21:15:45.999999]) #displayTimedeltaIndex print("TimedeltaIndex...\n", tdIndex) #ReturnadataframeofthecomponentsofTimeDeltas print("\nThe Dataframe of the components of TimeDeltas...\n", tdIndex.components) #RoundoperationonTimeDeltaIndexdatewithsecondsfrequency # For seconds frequency, we have used S print("\nPerforming round operation with seconds frequency...\n", tdIndex.round(freq=S))输出结果

这将产生以下代码-

TimedeltaIndex...
