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.yearres2 = period2.year
示例
以下是代码
import pandas as pd输出结果# 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)
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
