Python Pandas - 从 Period 对象中获取年份

要从Period对象获取年份，请使用period.year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("2020-09-23") period2 = pd.Period(freq="D", year = 2021, month = 4, day = 16, hour = 2, minute = 35)

显示期间对象

print("Period1...\n", period1) print("Period2...\n", period2)

从两个Period对象中获取年份

res1 = period1.year res2 = period2.year

示例

以下是代码

import pandas as pd #Thepandas.Period代表一段时间 #创建两个Period对象 period1 = pd.Period("2020-09-23") period2 = pd.Period(freq="D", year = 2021, month = 4, day = 16, hour = 2, minute = 35) #显示Period对象 print("Period1...\n", period1) print("Period2...\n", period2) #从两个Period对象中获取年份 res1 = period1.year res2 = period2.year #从两个Period对象返回年份 print("\nDisplay the Year from the 1st Period object ...\n", res1) print("\nDisplay the Year from the 2nd Period object...\n", res2)输出结果

这将产生以下代码

Period1... 2020-09-23 Period2... 2021-04-16 Display the Year from the 1st Period object ... 2020 Display the Year from the 2nd Period object... 2021
