Python Pandas - 從 TimeDeltaIndex 物件建立 DataFrame,忽略原始索引
要從 TimeDeltaIndex 物件建立 DataFrame,請使用 TimeDeltaIndex to_frame() 方法。忽略原始索引,使用帶有值False 的 index 引數。
首先,匯入必要的庫 −
import pandas as pd
建立一個 TimeDeltaIndex 物件。我們已使用“data”引數設定 timedelta 類資料 −
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)從 TimeDeltaIndex 物件建立一個 DataFrame。使用“False”引數在返回的 DataFrame 中不設定原始索引 −
print("\nTimeDeltaIndex to DataFrame...\n", tdIndex.to_frame(index=False))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)
# Create a DataFrame from TimeDeltaIndex object
# The original index isn't set in the returned DataFrame using the 'False' parameter
print("\nTimeDeltaIndex to DataFrame...\n", tdIndex.to_frame(index=False))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 TimeDeltaIndex to DataFrame... 0 0 4 days 08:20:00.000035045 1 0 days 17:42:19.999999 2 9 days 11:16:02.000055 3 0 days 22:35:25.000075
