Process running every second + a 2nd one to pull value

Hi guys,

I am trying to have one timer going, executing code every second and updating the value of a variable. At the same time, I want to do an ad-hoc pull (via WSIG) of the value to bring it to the web.

Essentially I want the value of a variable updating constantly, but being able to pull it at a given time via another function (thread?).

What should my approach be?

Thanks in advance!

I hope someone comes up with a good answer or explains that my answer is "good".

Code:

#code restored
import signal
import threading
import time

a = 0
more = True
semaphore = threading.Semaphore()

def change():
    global a,more
    for i in range(8):
        a = i
        semaphore.release()
        time.sleep(1)
    more = False
    semaphore.release()

threading.Thread(target=change).start()

old = a
while more:
    semaphore.acquire()
    print(a)
    old = a
