如何在一个月内获得序数平日

import datetime

def get_ordinal_weekday(year, month, weekday, ordinal):
    # 获取指定年月的第一个平日
    first_day = datetime.date(year, month, 1)
    while first_day.weekday() != weekday:
        first_day += datetime.timedelta(days=1)

    # 计算指定序数平日的日期
    ordinal_weekday = first_day + datetime.timedelta(weeks=ordinal-1)
    return ordinal_weekday

# 示例：获取2022年1月的第2个星期一
year = 2022
month = 1
weekday = 0  # 0表示星期一
ordinal = 2
result = get_ordinal_weekday(year, month, weekday, ordinal)
print(result)
