Python Pandas - 判断 PeriodIndex 对象中的日期是否属于闰年
要判断 PeriodIndex 对象中的日期是否属于闰年,请使用 periodIndex.is_leap_year 属性。
首先,导入必需的库 -
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)
检查日期是否是闰年 -
print("\nWhether the date is a leap year?\n", periodIndex.is_leap_year)示例
以下是代码 -
import pandas as pd
# Create a PeriodIndex object
# PeriodIndex is an immutable ndarray holding ordinal values indicating regular periods in time
# 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")
# Display PeriodIndex object
print("PeriodIndex...\n", periodIndex)
# Display PeriodIndex frequency
print("\nPeriodIndex frequency object...\n", periodIndex.freq)
# Display PeriodIndex frequency as string
print("\nPeriodIndex frequency object as a string...\n", periodIndex.freqstr)
# Check whether the date is a leap year
print("\nWhether the date is a leap year?\n", periodIndex.is_leap_year)输出
这将生成以下代码 -
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]
