What are some examples of thread synchronization in Python?

Thread synchronization in Python can be achieved using various techniques like locks, semaphores, and events. Would you like to know more about a specific technique?

Can you explain how to use locks for synchronization?

Sure! In Python, you can use the threading.Lock class to create a lock. You acquire the lock before accessing shared resources and release it afterward to prevent race conditions.

Could you provide a code example?

Absolutely! Here's a simple example:

import threading

lock = threading.Lock()

shared_resource = 0

def thread_function():
    global shared_resource
    with lock:
        for _ in range(100000):
            shared_resource += 1

threads = [threading.Thread(target=thread_function) for _ in range(2)]
for thread in threads:
    thread.start()
for thread in threads:
    thread.join()

print(shared_resource)  # Should print 200000

What are semaphores and how do they differ from locks?

Semaphores are similar to locks but allow a certain number of threads to access a resource simultaneously. Unlike locks, which are binary (locked/unlocked), semaphores can have a count that determines how many threads can hold the semaphore at once.
