Timeloop
Timeloop is a service that can be used to run periodic tasks after a certain interval.
Each job runs on a separate thread and when the service is shut down, it waits till all tasks currently being executed are completed.
Inspired by this blog here
Installation
pip install timeloop
Writing jobs
import time
from timeloop import Timeloop
from datetime import timedelta
tl = Timeloop()
@tl.job(interval=timedelta(seconds=2))
def sample_job_every_2s():
print "2s job current time : {}".format(time.ctime())
@tl.job(interval=timedelta(seconds=5))
def sample_job_every_5s():
print "5s job current time : {}".format(time.ctime())
@tl.job(interval=timedelta(seconds=10))
def sample_job_every_10s():
print "10s job current time : {}".format(time.ctime())
Start time loop in separate thread
By default timeloop starts in a separate thread.
Please do not forget to call tl.stop
before exiting the program, Or else the jobs wont shut down gracefully.
tl.start()
while True:
try:
time.sleep(1)
except KeyboardInterrupt:
tl.stop()
break
Start time loop in main thread
Doing this will automatically shut down the jobs gracefully when the program is killed, so no need to call tl.stop
tl.start(block=True)
