推荐答案

也许你可以使用这些函数来计算一个月的天数:

Maybe You can use these function to get count days of month:

import datetime


def get_month_days_count(year: int, month: int) -> int:
    date = datetime.datetime(year, month, 1)
    while (date + datetime.timedelta(days=1)).month == month:
        date = date + datetime.timedelta(days=1)
    return date.day
