如何统计不含节假日的工作天数？

import datetime

def count_working_days(start_date, end_date, holidays):
    working_days = 0
    current_date = start_date

    while current_date <= end_date:
        if current_date.weekday() < 5 and current_date not in holidays:
            working_days += 1
        current_date += datetime.timedelta(days=1)

    return working_days

# 示例用法
start_date = datetime.date(2022, 1, 1)
end_date = datetime.date(2022, 12, 31)
holidays = [datetime.date(2022, 1, 1), datetime.date(2022, 10, 1)]

working_days = count_working_days(start_date, end_date, holidays)
print("不含节假日的工作天数：", working_days)
