要以每小时的频率对 TimeDeltaIndex 执行地板操作,请使用方法。对于每小时频率,请使用值为'H'的freq参数。TimeDeltaIndex.floor()
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 =['5 day 8h 20min 35us 45ns', '+17:42:19.999999', '7 day 3h 08:16:02.000055', '+22:35:25.999999'])
显示 TimedeltaIndex -
print("TimedeltaIndex...\n", tdIndex)
TimeDeltaIndex 日期的楼层操作,每小时频率。对于每小时频率,我们使用了“H” -
print("\nPerforming Floor operation with hourly frequency...\n", tdIndex.floor(freq='H'))
以下是代码 -
import pandas as pd # Create a TimeDeltaIndex object # We have set the timedelta-like data using the 'data' parameter tdIndex = pd.TimedeltaIndex(data =['5 day 8h 20min 35us 45ns', '+17:42:19.999999', '7 day 3h 08:16:02.000055', '+22:35:25.999999']) # display TimedeltaIndex print("TimedeltaIndex...\n", tdIndex) # Return a dataframe of the components of TimeDeltas print("\nThe Dataframe of the components of TimeDeltas...\n", tdIndex.components) # Floor operation on TimeDeltaIndex date with hourly frequency # For hourly frequency, we have used 'H' print("\nPerforming Floor operation with hourly frequency...\n", tdIndex.floor(freq='H'))输出结果
这将产生以下代码 -
