I need to call function every x seconds but with option to call it manually and in this case reset time. I have sth like this:
import time
import threading
def printer():
print("do it in thread")
def do_sth(event):
while not event.is_set():
printer()
time.sleep(10)
event = threading.Event()
print("t - terminate, m - manual")
t = threading.Thread(target=do_sth, args=(event,))
t.daemon = True
t.start()
a = input()
if a == 't':
event.set()
elif a == 'm':
event.wait()
printer()
event.clear()
UPDATE: I have found something that helped me a lot: Python - Thread that I can pause and resume Now my code look like this:
import threading, time, sys
class ThreadClass(threading.Thread):
def __init__(self):
threading.Thread.__init__(self)
self.can_run = threading.Event()
self.thing_done = threading.Event()
self.thing_done.set()
self.can_run.set()
def run(self):
while True:
self.can_run.wait()
try:
self.thing_done.clear()
self.do_in_thread()
finally:
self.thing_done.set()
time.sleep(5)
def pause(self):
self.can_run.clear()
self.thing_done.wait()
def resume(self):
self.can_run.set()
def do_in_thread(self):
print("Thread...1")
time.sleep(2)
print("Thread...2")
time.sleep(2)
print("Thread...3")
def do_in_main():
print("Main...1")
time.sleep(2)
print("Main...2")
time.sleep(2)
print("Main...3")
if __name__ == '__main__':
t = ThreadClass()
t.daemon = True
t.start()
while True:
i = input()
if i == 'm':
t.pause()
do_in_main()
t.resume()
elif i == 't':
sys.exit()
# t.join()
The only problem is that when I terminate, a would like thread to finish its job before it exits.
It may be that buffered outputs are the culprits and thus - you're are getting your expected behaviour.
I changed your code to the following, and it seems to do something (if that's what you wanted, is up to you):
import time
import threading
def printer():
print("do it in thread")
def do_sth(event):
print("event.is_set:", event.is_set())
while not event.is_set():
printer()
time.sleep(10)
event = threading.Event()
print("t - terminate, m - manual")
t = threading.Thread(target=do_sth, args=(event,))
print("t:",t)
t.daemon = True
t.start()
a = input()
if a == 't':
event.set()
elif a == 'm':
event.wait()
printer()
event.clear()
