Python Pandas - 获取某个时期所在的月份中的某一天

2026-06-03 1 花语

要获取Period所在的月份的日期,请使用period.day 属性。

首先,导入所需的库-

import pandas as pd

的pandas.Period代表的一段时间。创建两个Period对象-

period1 = pd.Period("2021-09-18") period2 = pd.Period(freq =D, year = 2021, month = 9, day = 22, hour = 4, minute = 55)

从两个Period对象中获取月份中的第几天-

res1 = period1.day res2 = period2.day

示例

以下是代码-

import pandas as pd #Thepandas.Periodrepresentsaperiodoftime #creatingtwoPeriodobjects period1 = pd.Period("2021-09-18") period2 = pd.Period(freq =D, year = 2021, month = 9, day = 22, hour = 4, minute = 55) #displaythePeriodobjects print("Period1...\n", period1) print("Period2...\n", period2) #getthedayofthemonthfromtwoPeriodobjects res1 = period1.day res2 = period2.day #ReturnthedayofthemonthfromthetwoPeriodobjects print("\nDay of the month from the 1st Period object ...\n", res1) print("\nDay of the month from the 2nd Period object...\n", res2)输出结果

这将产生以下代码-

Period1... 2021-09-18 Period2... 2021-09-22 Day of the month from the 1st Period object ... 18 Day of the month from the 2nd Period object... 22
