法律Python Pandas - 创建 TimeDeltaIndex 对象
要创建 TimeDeltaIndex 对象，请使用 **pandas.TimedeltaIndex() **方法。
首先，导入所需的库 -
import pandas as pd
创建 TimeDeltaIndex 对象。我们已使用“data”参数设置了时差数据 -
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)返回时差组件的数据框 -
print("\nThe Dataframe of the components of TimeDeltas...\n", tdIndex.components)示例
以下为代码 -
import pandas as pd
# Create a TimeDeltaIndex object
# 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'])
# display TimedeltaIndex
print("TimedeltaIndex...\n", tdIndex)
# display the number of days from each element of TimeDeltaIndex
print("\nThe number of days from the TimeDeltaIndex object...\n", tdIndex.days)
# display the number of seconds from each element of TimeDeltaIndex
print("\nThe number of seconds from the TimeDeltaIndex object...\n", tdIndex.seconds)
# display the number of microseconds from each element of TimeDeltaIndex
print("\nThe number of microseconds from the TimeDeltaIndex object...\n", tdIndex.microseconds)
# Return a dataframe of the components of TimeDeltas
print("\nThe Dataframe of the components of TimeDeltas...\n", tdIndex.components)输出
这将生成以下代码 -
TimedeltaIndex... TimedeltaIndex(['10 days 05:02:00.000003010', '0 days 22:39:19.999999', '2 days 07:08:02.000045', '0 days 21:15:45.999999'], dtype='timedelta64[ns]', freq=None) The number of days from the TimeDeltaIndex object...
