Python:将作业安排在两个预定义的时间之间运行

Question

我试图在两个预定义的时间内执行一个命令；

这是我到目前为止所拥有的

##Time
day_of_week = datetime.date.today().weekday() # 0 is Monday, 6 is Sunday
time = datetime.datetime.now().time()

if day_of_week < 5 and (time > datetime.time(17) and time < datetime.time(5)):  
    print "True"

它似乎在1700年后执行刚刚好，但一旦时间转到第二天，超过万，它根本不运行。任何帮助都将不胜感激。谢谢

Answer 1

time > datetime.time(17) and time < datetime.time(5)

东西怎么能超过17，小于5呢？

也许：

if ((day_of_week < 5 and time > datetime.time(17)) or
    (0 < day_of_the_week < 6 and time < datetime.time(5))):

Answer 2

问题在于您的状况，(time > datetime.time(17) and time < datetime.time(5))。time不能同时拥有超过17小时和<5小时的时间。

通过一步一步地思考这一点可能会有所帮助：

    ##Time
    from datetime import datetime, date, time, timedelta

    # when to run the job
    time_of_day_min = time(17)
    time_of_day_max = time(5)
    weekdays_min = [0,1,2,3,4] # run Mon-Fri after 17.00
    weekdays_max = [1,2,3,4,5] # run Tue-Sat before 05.00

    # current day and time
    day_of_week = date.today().weekday() # 0 is Monday, 6 is Sunday
    now_time = datetime.now()

    # figure out if it runs between 17.00 - 23.59, or 00.00 - 05.00
    run_before_midnight = now_time >= time_of_day_min 
    run_after_midnight = now_time <= time_of_day_max

    # check if conditions are met. Note the *or*
    if (day_of_week in weekdays_min and run_before_midnight) or \
       (day_of_week in weekdays_max and run_after_midnight):
        print "Running!"
