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'))
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 =['10 day 5h 2 min 3us 10ns', '+22:39:19.999999', '2 day 4h 03:08:02.000045', '+21:15:45.999999']) # 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) # Round operation on TimeDeltaIndex date with minute frequency # 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 -
