To ensure secure parallel operation of components in Python, synchronization mechanisms such as locks (Lock), semaphores (Semaphore), and events (Event) from the threading module are usually used. They prevent simultaneous access to shared resources, avoiding race conditions.
If multi-processing (multiprocessing) is used, queues (Queue) or managers (Manager) are employed for data exchange, ensuring correct communication between processes.
Example using a lock:
import threading
lock = threading.Lock()
shared_resource = 0
def safe_increment():
global shared_resource
with lock:
temp = shared_resource
temp += 1
shared_resource = temp
threads = [threading.Thread(target=safe_increment) for _ in range(100)]
for t in threads:
t.start()
for t in threads:
t.join()
print(shared_resource) # Expected 100
You can also use higher-level structures like queue.Queue, which is thread-safe by design.
