要将 Period 对象作为具有年频率的时间戳返回,请使用该方法并将 freq 参数设置为“ Y ”。period.to_timestamp()
首先,导入所需的库 -
import pandas as pd
的pandas.Period代表的一段时间。创建 Period 对象
period = pd.Period(freq="S", year = 2021, month = 9, day = 18, hour = 17, minute = 20, second = 45)
显示 Period 对象
print("Period...\n", period)
返回 Period 对象的时间戳表示。我们已经使用“freq”参数设置了频率。频率设置为“Y”,即每年
print("\nPeriod to Timestamp with yearly (year-end) frequency...\n", period.to_timestamp(freq='Y'))
以下是代码
import pandas as pd # Thepandas.Period 代表一段时间 # 创建 Period 对象 period = pd.Period(freq="S", year = 2021, month = 9, day = 18, hour = 17, minute = 20, second = 45) # 显示 Period 对象 print("Period...\n", period) # 返回 Period 对象的时间戳表示 # 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'))输出结果
这将产生以下代码
Period... 2021-09-18 17:20:45 Period to Timestamp with yearly (year-end) frequency... 2021-12-31 00:00:00
