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。
代码语言:javascript复制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,http://www.sharejs.com
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)
