Python Pandas - 如何以微秒频率舍入 TimeDeltaIndex
要以微秒频率舍入TimeDeltaIndex，请使用该方法。对于微秒频率，使用值为'us'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', '+07:20:32.261811624'])
显示TimedeltaIndex-
print("TimedeltaIndex...\n", tdIndex)以微秒频率对TimeDeltaIndex日期进行舍入操作。对于微秒频率，我们使用了“我们”-
print("\nPerforming round operation with microseconds frequency...\n",
tdIndex.round(freq='us'))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', '+07:20:32.261811624'])
#displayTimedeltaIndex
print("TimedeltaIndex...\n", tdIndex)
#ReturnadataframeofthecomponentsofTimeDeltas
print("\nThe Dataframe of the components of TimeDeltas...\n", tdIndex.components)
#RoundoperationonTimeDeltaIndexdatewithmicrosecondsfrequency
# For microseconds frequency, we have used 'us'
print("\nPerforming round operation with microseconds frequency...\n",
tdIndex.round(freq='us'))输出结果这将产生以下代码-
