两个日期之间的每月天数

import datetime

def get_monthly_days(start_date, end_date):
    start_year = start_date.year
    start_month = start_date.month
    end_year = end_date.year
    end_month = end_date.month

    monthly_days = []

    for year in range(start_year, end_year + 1):
        start = start_month if year == start_year else 1
        end = end_month if year == end_year else 12

        for month in range(start, end + 1):
            if month in [1, 3, 5, 7, 8, 10, 12]:
                monthly_days.append(31)
            elif month in [4, 6, 9, 11]:
                monthly_days.append(30)
            else:
                if year % 4 == 0 and (year % 100 != 0 or year % 400 == 0):
                    monthly_days.append(29)
                else:
                    monthly_days.append(28)

    return monthly_days

# 示例用法
start_date = datetime.date(2022, 1, 15)
end_date = datetime.date(2022, 5, 10)
days = get_monthly_days(start_date, end_date)
print(days)
