Python Pandas - 从 TimeDeltaIndex 中提取每个元素的纳秒数

要从TimeDeltaIndex对象中提取每个元素的微秒数，请使用TimedeltaIndex.nanoseconds属性。

首先，导入所需的库-

import pandas as pd

创建一个TimeDeltaIndex对象。我们也使用data参数设置了类似timedelta的数据-

tdIndex = pd.TimedeltaIndex(data =[10 day 5h 2 min 35s 3us 10ns, +22:39:19.999999, 2 day 4h 03:08:02.000045, +21:15:45.999999])

显示TimeDeltaIndex的每个元素的纳秒数-

print("\nThe number of nanoseconds from the TimeDeltaIndex object...\n", tdIndex.nanoseconds)

示例

以下是代码-

import pandas as pd #CreateaTimeDeltaIndexobject # We have set the timedelta-like data using the data parameter as well tdIndex = pd.TimedeltaIndex(data =[10 day 5h 2 min 35s 3us 10ns, +22:39:19.999999, 2 day 4h 03:08:02.000045, +21:15:45.999999]) #displayTimedeltaIndex print("TimedeltaIndex...\n", tdIndex) #displaythenumberofnanosecondsfromeachelementofTimeDeltaIndex print("\nThe number of nanoseconds from the TimeDeltaIndex object...\n", tdIndex.nanoseconds) #ReturnadataframeofthecomponentsofTimeDeltas print("\nThe Dataframe of the components of TimeDeltas...\n", tdIndex.components)输出结果

这将产生以下代码-

TimedeltaIndex...
