定時作業

signalに呼んでもらう。

import time,  signal

def foo( signum, frame ):
    print(time.time())

if ( '__main__' == __name__):

    interval_1st = 0.1 # seconds
    interval_after1st = 0.1 # seconds

    signal.signal(signal.SIGALRM, foo)
    signal.setitimer(signal.ITIMER_REAL, interval_1st, interval_after1st) 

  it = 10

    while ( it > 0 ):
        signal.pause() # until signal
        it-=1


    # Stop timer
    signal.setitimer(signal.ITIMER_REAL, 0)
    signal.signal( signal.SIGALRM, sgnal.SIG_DFL )
