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
