法律研究Python Pandas - 从周期对象中获取年份的季度
要获取周期的时间组件，请使用 period.quarter 属性。首先导入所需的库-
import pandas as pd
pandas.Period 表示一段时间。创建两个 Period 对象
period1 = pd.Period("2020-02-27 08:32:48")
period2 = pd.Period(freq="M", year = 2021, month = 8, day = 16, hour = 2, minute = 35)显示 Period 对象
print("Period1...\n", period1)
print("Period2...\n", period2)从两个 Period 对象中获取年份季度
res1 = period1.quarter res2 = period2.quarter
结果基于一年的以下季度
Quarter 1 = 1st January to 31st March Quarter 2 = 1st April to 30th June Quarter 3 = 1st July to 30th September Quarter 4 = 1st October to 31st December
示例
以下是代码
import pandas as pd
# The pandas.Period represents a period of time
# creating two Period objects
period1 = pd.Period("2020-02-27 08:32:48")
period2 = pd.Period(freq="M", year = 2021, month = 8, day = 16, hour = 2, minute = 35)
# display the Period objects
print("Period1...\n", period1)
print("Period2...\n", period2)
# get the quarter of the year from two Period objects
res1 = period1.quarter
res2 = period2.quarter
# Return the quarter from the two Period objects
# Result is based on the following quarters of an year:
# Quarter 1 = 1st January to 31st March
# Quarter 2 = 1st April to 30th June
# Quarter 3 = 1st July to 30th September
# Quarter 4 = 1st October to 31st December
print("\nQuarter from the 1st Period object ...\n", res1)
print("\nQuarter from the 2nd Period object...\n", res2)输出
将生成以下代码
Period1... 2020-02-27 08:32:48 Period2... 2021-08 Quarter from the 1st Period object ... 1 Quarter from the 2nd Period object... 3
