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)
