python 计算两日期之间工作日时长

1. 代码

def exclude_weekend_time():

    from dateutil import rrule

    start_date = datetime.datetime.strptime('2019-04-19 13:21:46', '%Y-%m-%d %H:%M:%S')

    end_date = datetime.datetime.strptime('2019-04-22 13:21:46', '%Y-%m-%d %H:%M:%S')

    days_off = 5, 6

    workdays = [x for x in range(7) if x not in days_off]

    secondly = rrule.rrule(rrule.SECONDLY, dtstart=start_date, until=end_date, byweekday=workdays)

    seconds = secondly.count()

    print(seconds)

if __name__ == '__main__':

    exclude_weekend_time()

2. 如果计算相隔年，或相隔月份，相隔天数，可以修改规则

# 间隔秒数
secondly = rrule.rrule(rrule.SECONDLY, dtstart=start_date, until=end_date, byweekday=workdays)
 
# 间隔分钟数
secondly = rrule.rrule(rrule.MINUTELY, dtstart=start_date, until=end_date, byweekday=workdays)
 
# 间隔小时数
secondly = rrule.rrule(rrule.HOURLY, dtstart=start_date, until=end_date, byweekday=workdays)
 
# 间隔天数
secondly = rrule.rrule(rrule.DAILY, dtstart=start_date, until=end_date, byweekday=workdays)
 
... ...
