windows下python设置定时任务（定时执行脚本）

源码如下：

import os,time
import sys

def DeltaSeconds():
    SECONDS_PER_DAY = 24 * 60 * 60
    from datetime import datetime, timedelta
    curTime = datetime.now()
    desTime = curTime.replace(hour=19, minute=7, second=1, microsecond=0)  #这里添加时间
    delta = desTime - curTime
    skipSeconds = delta.total_seconds() % SECONDS_PER_DAY
    print "Must sleep %d seconds" % skipSeconds
    return skipSeconds


while True:

    s = DeltaSeconds()
    time.sleep(s)
    print "work it!"  #这里可以替换成作业
