Pandas Python - 返回頻率為每天的時間戳作為週期物件
若要將週期物件作為時間戳返回,並以每日頻率顯示,請使用 period.to_timestamp() 方法,並將 freq 引數設定為“D”。
首先,匯入必要的庫 -
import pandas as pd
表示一段時間間隔的 pandas.Period。建立一個週期物件
period = pd.Period(freq="S", year = 2021, month = 11, day = 26, hour = 11, minute = 45, second = 55)
顯示週期物件
print("Period...\n", period)
返回週期物件的時間戳表示形式。我們已使用“freq”引數設定頻率。頻率設定為“D”,即每天
print("\nPeriod to Timestamp with daily frequency...\n", period.to_timestamp(freq='D'))
示例
以下為程式碼
import pandas as pd # The pandas.Period represents a period of time # Creating a Period object period = pd.Period(freq="S", year = 2021, month = 11, day = 26, hour = 11, minute = 45, second = 55) # display the Period object print("Period...\n", period) # Return the Timestamp representation of the Period object # We have set the frequency using the "freq" parameter # The frequency is set as 'D' i.e. daily print("\nPeriod to Timestamp with daily frequency...\n", period.to_timestamp(freq='D'))
輸出
這將生成以下程式碼
Period... 2021-11-26 11:45:55 Period to Timestamp with daily frequency... 2021-11-26 00:00:00
