An equivalent to Java volatile in Python

Question

Does Python have the equivalent of the Java volatile concept?

In Java there is a keyword volatile. As far as I know, when we use vola

Answer 1

The keyword "global" is what you are looking for:

import threading

queue = []
l = threading.Lock()

def f():
    global queue
    l.acquire()
    queue.append(1)
    l.release()

def g():
    print(queue)

threads = [
    threading.Thread(target=f),
    threading.Thread(target=g)
]
for t in threads:
    t.start()
for t in threads:
    t.join()
