How can I synchronize threads in Python?

How can I synchronize threads in Python?

You can use the threading module, specifically the Lock class, to synchronize threads.

Can you show me a simple example of using a Lock?

Sure! Here's a basic example:

import threading

lock = threading.Lock()

def thread_function(name):
    with lock:
        print(f'Thread {name}: starting')
        # Simulate some work
        print(f'Thread {name}: finishing')

threads = []
for index in range(3):
    thread = threading.Thread(target=thread_function, args=(index,))
    threads.append(thread)
    thread.start()

for thread in threads:
    thread.join()

What happens if I don't use a Lock?

Without a Lock, multiple threads may access shared resources simultaneously, leading to race conditions and unpredictable behavior.

Are there other synchronization primitives in Python?

Yes, Python also provides other synchronization primitives like Event, Condition, and Semaphore for different use cases.
