法律研究Python Pandas - 从 TimeDeltaIndex 中提取每个元素的纳秒数
要从 TimeDeltaIndex 对象中提取每个元素的纳秒数，请使用 TimedeltaIndex.nanoseconds 属性。
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 timedelta 类似数据 −
tdIndex = pd.TimedeltaIndex(data =['10 day 5h 2 min 35s 3us 10ns', '+22:39:19.999999', '2 day 4h 03:08:02.000045', '+21:15:45.999999'])
显示 TimeDeltaIndex 中每个元素的纳秒数 −
print("\nThe number of nanoseconds from the TimeDeltaIndex object...\n",
tdIndex.nanoseconds)示例
以下是代码 −
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 35s 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 nanoseconds from each element of TimeDeltaIndex
print("\nThe number of nanoseconds from the TimeDeltaIndex object...\n",
tdIndex.nanoseconds)
# 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 05:02:35.000003010', '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 nanoseconds from the TimeDeltaIndex object... Int64Index([10, 0, 0, 0], dtype='int64') The Dataframe of the components of TimeDeltas... days hours minutes seconds milliseconds microseconds nanoseconds 0 10 5 2 35 0 3 10 1 0 22 39 19 999 999 0 2 2 7 8 2 0 45 0 3 0 21 15 45 999 999 0
