Python Pandas - 返回应用于给定 Period 对象的时间序列频率的字符串别名

要返回应用于给定Period对象的时间序列频率的字符串别名，请使用period.freqstr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 03:55:20") period2 = pd.Period(freq="Y", year = 2021, month = 2, day = 14, hour = 2, minute = 35)

显示Period对象-

print("Period1...\n", period1) print("Period2...\n", period2)

获取频率的字符串别名-

res1 = period1.freqstr res2 = period2.freqstr

示例

以下是代码-

import pandas as pd #Thepandas.Period表示一段时间 #创建两个Period对象 period1 = pd.Period("2020-09-23 03:55:20") period2 = pd.Period(freq="Y", year = 2021, month = 2, day = 14, hour = 2, minute = 35) #显示Period对象 print("Period1...\n", period1) print("Period2...\n", period2) #获取频率的字符串别名 res1 = period1.freqstr res2 = period2.freqstr #从两个Period对象返回频率的字符串别名 print("\nString alias of the frequency from the 1st Period object ...\n", res1) print("\nString alias of the frequency from the 2nd Period object ...\n", res2)输出结果

这将产生以下代码-

Period1... 2020-09-23 03:55:20 Period2... 2021 String alias of the frequency from the 1st Period object ... <Second> String alias of the frequency from the 2nd Period object ... <YearEnd: month=12>
