法律學Python Pandas——從 TimeDeltaIndex 提取每個元素的秒數
要從 TimeDeltaIndex 物件中提取每個元素的秒數，請使用 TimedeltaIndex.seconds 屬性
首先，匯入所需的庫 −
import pandas as pd
建立一個 TimeDeltaIndex 物件。我們已經使用 'data' 引數設定了類似時間增量的資料 −
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'])
顯示 TimedeltaIndex −
print("TimedeltaIndex...\n", tdIndex)從 TimeDeltaIndex 的每個元素中顯示秒數 −
print("\nThe number of seconds from the TimeDeltaIndex object...\n", tdIndex.seconds)示例
以下為程式碼 −
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 seconds from each element of TimeDeltaIndex
print("\nThe number of seconds from the TimeDeltaIndex object...\n", tdIndex.seconds)
# Return a dataframe of the components of TimeDeltas
print("\nThe Dataframe of the components of TimeDeltas...\n", tdIndex.components)輸出
這將生成以下程式碼 −
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 seconds from the TimeDeltaIndex object... Int64Index([18155, 81559, 25682, 76545], 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
