Python Pandas - 创建一个 TimeDeltaIndex 对象
要创建TimeDeltaIndex对象，请使用该方法。pandas.TimedeltaIndex()
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 3us 10ns', '+22:39:19.999999', '2 day 4h 03:08:02.000045', '+21:15:45.999999'])
显示TimedeltaIndex-
print("TimedeltaIndex...\n", tdIndex)返回TimeDeltas组件的数据帧-
print("\nThe Dataframe of the components of TimeDeltas...\n", tdIndex.components)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 3us 10ns', '+22:39:19.999999',
'2 day 4h 03:08:02.000045', '+21:15:45.999999'])
#displayTimedeltaIndex
print("TimedeltaIndex...\n", tdIndex)
#displaythenumberofdaysfromeachelementofTimeDeltaIndex
print("\nThe number of days from the TimeDeltaIndex object...\n", tdIndex.days)
#displaythenumberofsecondsfromeachelementofTimeDeltaIndex
print("\nThe number of seconds from the TimeDeltaIndex object...\n", tdIndex.seconds)
#displaythenumberofmicrosecondsfromeachelementofTimeDeltaIndex
print("\nThe number of microseconds from the TimeDeltaIndex object...\n", tdIndex.microseconds)
#ReturnadataframeofthecomponentsofTimeDeltas
print("\nThe Dataframe of the components of TimeDeltas...\n", tdIndex.components)输出结果这将产生以下代码-
