How can I achieve synchronization in Python threading?

You can achieve synchronization in Python threading using locks, events, or semaphores. Would you like an example?

Yes, please provide an example using locks.

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

import threading

lock = threading.Lock()

def synchronized_function():
    with lock:
        # critical section of code
        print('Thread is accessing the shared resource')

thread1 = threading.Thread(target=synchronized_function)
thread2 = threading.Thread(target=synchronized_function)

thread1.start()
thread2.start()

thread1.join()
thread2.join()

What happens if I don't use a lock?

If you don't use a lock, multiple threads may access the shared resource simultaneously, leading to race conditions and unpredictable behavior.
