How can I handle thread synchronization in Python?

You can use threading locks, events, or semaphores to manage thread synchronization in Python. Would you like examples?

Yes, please provide an example using locks.

Sure! Here's a simple example using a Lock:

import threading

lock = threading.Lock()

def thread_safe_increment(counter):
    for _ in range(1000):
        lock.acquire()
        counter[0] += 1
        lock.release()

counter = [0]
threads = [threading.Thread(target=thread_safe_increment, args=(counter,)) for _ in range(10)]

for thread in threads:
    thread.start()

for thread in threads:
    thread.join()

print(counter[0])  # Should print 10000

What are the differences between locks and semaphores?

Locks allow only one thread to access a resource at a time, while semaphores can allow multiple threads to access a resource, up to a specified limit.

Can you explain how to use events for synchronization?

Certainly! Events are used to signal between threads. You can create an Event object and use its set() and wait() methods to control thread execution.
