Python Pandas - 获取某个时期所在的月份中的某一天
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
