Python学习记录_每个一段时间执行任务

因为需求比较简单, 所以最后用了while True: + time.sleep()解决的.

小树苗代码

#Function: 每隔一段时间做一个事情   
from datetime import date, time, datetime, timedelta

#要做的事情   
def work():
    print ('hello world.')
def runTask(func, day=0, hour=0, min=0, second=0):
# Init time
    now = datetime.now()
    strnow = now.strftime('%Y-%m-%d %H:%M:%S')
    print ('now:',strnow)
    # First next run time
    period = timedelta(days=day, hours=hour, minutes=min, seconds=second)
    next_time = now + period
    strnext_time = next_time.strftime('%Y-%m-%d %H:%M:%S')
    print ('next run:',strnext_time)
    while True:
        # Get system current time
        iter_now = datetime.now()
        iter_now_time = iter_now.strftime('%Y-%m-%d %H:%M:%S')
        if str(iter_now_time) == str(strnext_time):
            # Get every start work time
            print ('start work: %s' % iter_now_time)
            # Call task func
            work()
            print ('task done.')
            # Get next iteration time
            iter_time = iter_now + period
            strnext_time = iter_time.strftime('%Y-%m-%d %H:%M:%S')
            print ('next_iter: %s' % strnext_time)
            # Continue next iteration
            continue
# runTask(work, min=0.5)
runTask(work(), day=0, hour=0, min=0,second=10)

我的代码

while True:
    time.sleep(1000)
    run_work()
