这篇文章主要介绍了python每隔N秒运行指定函数的方法,涉及Python的线程与时间操作技巧,非常具有实用价值,需要的朋友可以参考下
这是一个类似定时器的效果，每隔指定的秒数运行指定的函数，采用线程实现，代码简单实用。
代码如下:import os
import time
def print_ts(message):
print "[%s] %s"%(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime()), message)
def run(interval, command):
print_ts("-"*100)
print_ts("Command %s"%command)
print_ts("Starting every %s seconds."%interval)
print_ts("-"*100)
while True:
try:
# sleep for the remaining seconds of interval
time_remaining = interval-time.time()%interval
print_ts("Sleeping until %s (%s seconds)..."%((time.ctime(time.time()+time_remaining)), time_remaining))
time.sleep(time_remaining)
print_ts("Starting command.")
# execute the command
status = os.system(command)
print_ts("-"*100)
print_ts("Command status = %s."%status)
except Exception, e:
print e
if __name__=="__main__":
interval = 5
command = r"ipconfig"
run(interval, command)
希望本文所述对大家的Python程序设计有所帮助。
可以使用apscheduler模块Python code?
123456789101112131415161718
from apscheduler.schedulers.blocking import BlockingSchedulerfrom datetime import datetimeimport timeimport os def tick():print 'Tick! The time is: %s' % datetime.now() #每隔三秒执行一次if __name__ == '__main__':scheduler = BlockingScheduler()scheduler.add_job(tick,'cron',second='*/3',hour='*')print 'Press Ctrl+{0} to exit'.format('Break' if os.name == 'nt' else 'C')try:scheduler.start()except KeyboardInterrupt,SystemExit:scheduler.shutdown()
