获取每个月的周数

import datetime

def get_weeks_in_month(year, month):
    first_day = datetime.date(year, month, 1)
    last_day = datetime.date(year, month, 28) + datetime.timedelta(days=4)
    last_day = last_day - datetime.timedelta(days=last_day.weekday())

    first_week = first_day.isocalendar()[1]
    last_week = last_day.isocalendar()[1]

    if last_week == 1 and first_day.month == 12:
        last_week = 53

    return last_week - first_week + 1

# 示例用法
year = 2022
month = 1
weeks_in_month = get_weeks_in_month(year, month)
print(f"The number of weeks in {year}-{month} is {weeks_in_month}.")
