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
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
