Python Pandas - 對具有微秒頻率的 TimeDeltaIndex 物件執行向上取整操作
要對具有微秒頻率的 TimeDeltaIndex 執行向上取整操作,請使用 **TimeDeltaIndex.ceil()** 方法。對於微秒頻率,請使用 **freq** 引數,其值為 **‘us’**。
首先,匯入所需的庫 -
import pandas as pd
建立一個 TimeDeltaIndex 物件。我們使用 'data' 引數設定了類似時間增量的資料 -
tdIndex = pd.TimedeltaIndex(data =['4 day 8h 20min 35us 45ns', '+17:42:19.999999', '9 day 3h 08:16:02.000055', '+22:35:25.000075'])
顯示 TimedeltaIndex -
print("TimedeltaIndex...\n", tdIndex)對具有微秒頻率的 TimeDeltaIndex 日期執行向上取整操作。對於微秒頻率,我們使用了 'us' -
print("\nPerforming Ceil operation with microseconds frequency...\n",
tdIndex.ceil(freq='us'))示例
以下是程式碼 -
import pandas as pd
# Create a TimeDeltaIndex object
# We have set the timedelta-like data using the 'data' parameter
tdIndex = pd.TimedeltaIndex(data =['4 day 8h 20min 35us 45ns', '+17:42:19.999999',
'9 day 3h 08:16:02.000055', '+22:35:25.000075'])
# 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)
# Ceil operation on TimeDeltaIndex date with microseconds frequency
# For microseconds frequency, we have used 'us'
print("\nPerforming Ceil operation with microseconds frequency...\n",
tdIndex.ceil(freq='us'))輸出
這將生成以下程式碼 -
TimedeltaIndex... TimedeltaIndex(['4 days 08:20:00.000035045', '0 days 17:42:19.999999', '9 days 11:16:02.000055', '0 days 22:35:25.000075'], dtype='timedelta64[ns]', freq=None) The Dataframe of the components of TimeDeltas... days hours minutes seconds milliseconds microseconds nanoseconds 0 4 8 20 0 0 35 45 1 0 17 42 19 999 999 0 2 9 11 16 2 0 55 0 3 0 22 35 25 0 75 0 Performing Ceil operation with microseconds frequency...
