法律研究Python Pandas - 以年頻率將 Period 物件返回為時間戳
要將 Period 物件以年頻率返回為時間戳，請使用 period.to_timestamp() 方法，並設定 freq 引數為 ‘Y’。
首先，匯入所需的庫 −
import pandas as pd
pandas.Period 表示一個時間段。建立一個 Period 物件
period = pd.Period(freq="S", year = 2021, month = 9, day = 18, hour = 17, minute = 20, second = 45)
顯示 Period 物件
print("Period...\n", period)返回 Period 物件的時間戳表示形式。我們使用 "freq" 引數設定了頻率。頻率設定為 'Y'，即每年
print("\nPeriod to Timestamp with yearly (year-end) frequency...\n", period.to_timestamp(freq='Y'))
示例
以下是程式碼
import pandas as pd
# The pandas.Period represents a period of time
# Creating a Period object
period = pd.Period(freq="S", year = 2021, month = 9, day = 18, hour = 17, minute = 20, second = 45)
# 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 'Y' i.e. yearly
print("\nPeriod to Timestamp with yearly (year-end) frequency...\n", period.to_timestamp(freq='Y'))輸出
這將會生成以下程式碼
Period... 2021-09-18 17:20:45 Period to Timestamp with yearly (year-end) frequency... 2021-12-31 00:00:00
