法学研究Python Pandas——从 Period 对象中获取年份
若要从 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
pandas.Period 表示一个时间段。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 对象获取年份
res1 = period1.year res2 = period2.year
示例
以下为该代码
import pandas as pd
# The pandas.Period represents a period of time
# creating two Period objects
period1 = pd.Period("2020-09-23")
period2 = pd.Period(freq="D", year = 2021, month = 4, day = 16, hour = 2, minute = 35)
# display the Period objects
print("Period1...\n", period1)
print("Period2...\n", period2)
# get the year from two Period objects
res1 = period1.year
res2 = period2.year
# Return the year from the two Period objects
print("\nDisplay the Year from the 1st Period object ...\n", res1)
print("\nDisplay the Year from the 2nd Period object...\n", res2)输出
这会生成以下代码
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
