如何返回每个星期一的天数

import datetime

def get_mondays(year, month):
    mondays = []
    date = datetime.date(year, month, 1)
    while date.weekday() != 0:  # 找到第一个星期一
        date = date + datetime.timedelta(days=1)
    while date.month == month:  # 循环找到该月所有星期一
        mondays.append(date.day)
        date = date + datetime.timedelta(days=7)
    return mondays

year = 2022
month = 1
mondays = get_mondays(year, month)
print(mondays)
