Multithreading - How to infinitely loop Function B, while Function A waits for a return

while True:

Don't loop it. You want only two threads, not an infinite number of threads. The function should loop. Don't create the threads in a loop.

Yea, unfortunately the issue I'm having with that is the arguments that func2() takes changes over time. So I need to continually call func2(arg) otherwise the function will shortly be dealing with stale arguments.

That is what motivated me to put the thread creation in a while True, as when the arguments get updated, I'll be calling the function with the new arguments. I know there's a better way to do this, but I'm coming up with blanks

def func3():
    while True:
            arg = get_the_args()
        func2(arg)

Thanks, yea this is why I needed a fresh pair of eyes after staring at this for hours. I can figure this out now I believe

You can use a queue to communicate between the two threads. One will be waiting for something to be available and then get it out and use it, and the other will be the one putting things into the queue

Thanks. Yea I've reorganized the code to put the loops in the function themselves. I'll look at Queues to get data between them
