Python Pandas - 指示 PeriodIndex 对象中的日期是否属于闰年

2026-06-03 1 花语

要指示PeriodIndex对象中的日期是否属于闰年，请使用periodIndex.is_leap_year属性。

首先，导入所需的库-

import pandas as pd

创建一个PeriodIndex对象-

periodIndex = pd.PeriodIndex([2021-09-25 07:50:35, 2019-10-30 04:35:45, 2016-07-15 02:25:15, 2020-06-25 09:20:55], freq="T")

显示PeriodIndex对象-

print("PeriodIndex...\n", periodIndex)

检查日期是否为闰年-

print("\nWhether the date is a leap year?\n", periodIndex.is_leap_year)

示例

以下是代码-

import pandas as pd #CreateaPeriodIndexobject #PeriodIndexisanimmutablendarrayholdingordinalvaluesindicatingregularperiodsintime # We have set the frequency using the "freq" parameter periodIndex = pd.PeriodIndex([2021-09-25 07:50:35, 2019-10-30 04:35:45, 2016-07-15 02:25:15, 2020-06-25 09:20:55], freq="T") #DisplayPeriodIndexobject print("PeriodIndex...\n", periodIndex) #DisplayPeriodIndexfrequency print("\nPeriodIndex frequency object...\n", periodIndex.freq) #DisplayPeriodIndexfrequency as string print("\nPeriodIndex frequency object as a string...\n", periodIndex.freqstr) #Checkwhetherthedateisaleapyear print("\nWhether the date is a leap year?\n", periodIndex.is_leap_year)输出结果

这将产生以下代码-

PeriodIndex... PeriodIndex([2021-09-25 07:50, 2019-10-30 04:35, 2016-07-15 02:25,2020-06-25 09:20], dtype=period[T]) PeriodIndex frequency object... <Minute> PeriodIndex frequency object as a string... T Whether the date is a leap year? [False False True True]
