Python Pandas - 如何以分钟频率舍入 TimeDeltaIndex

要以分钟频率舍入TimeDeltaIndex，请使用方法。对于分钟频率，使用值为T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])

以分钟频率对TimeDeltaIndex日期进行舍入操作。对于分钟频率，我们使用了“T”-

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

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) #RoundoperationonTimeDeltaIndexdatewithminutefrequency # For minute frequency, we have used T print("\nPerforming round operation with minute frequency...\n", tdIndex.round(freq=T))输出结果

这将产生以下代码-

TimedeltaIndex...
