Python Pandas - 将周期对象作为具有月频的时间戳返回
若要将周期对象作为具有月频的时间戳返回,请使用 period.to_timestamp() 方法,并将 freq 参数设为“M”。
首先,导入所需的库 −
import pandas as pd
pandas.Period 表示一段时间。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。我们已通过使用“freq”参数设置频率。频率设置为“M”,即每月
print("\nPeriod to Timestamp with monthly (month-end) frequency...\n", period.to_timestamp(freq='M'))
示例
以下是代码
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 'M' i.e. monthly print("\nPeriod to Timestamp with monthly (month-end) frequency...\n", period.to_timestamp(freq='M'))
输出
这将生成以下代码
Period... 2021-09-18 17:20:45 Period to Timestamp with monthly (month-end) frequency... 2021-09-30 00:00:00
