Get return value of python class function after timer

Question

I have a simple python class called Timer_ that takes an interval in seconds and runs the timer in the background. When it is done, it runs a finished function that returns true. How would I get the value of this function when the timer stops in the form of a variable? Thank you!

import threading



class Timer_():

    def __init__(self, interval):
        #interval in seconds
        self.interval = interval
        self.finished = False

    def run(self):
        self.timel = threading.Timer(float(self.interval), self.finish)
        self.timel.start()

    def finish(self):
        self.finished = True
        return True

    def cancel(self):
        self.timel.cancel()



time = Timer_(5)
time.run()
print(time.finished)

Yes when the timer finishes I would like to store a python variable outside of the class — Nick D, Aug 23 '18 at 14:15

Sounds like you want to wait until time.finished is True

Try using a while loop over the value of time.finished:

time = Timer_(5)
timer.run()
while not timer.finished:
    pass
x = timer.finished
print(x)

This will loop through the while until timer.finished is True then you can use that value as a variable or continue on.
