How do I use threading locks in Python?

You can use the threading.Lock class to create a lock object. This helps prevent race conditions by ensuring that only one thread can access a resource at a time.

Can you show me a simple example?

Sure! Here's a basic example:

import threading

lock = threading.Lock()

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

This ensures that the print statement is executed by only one thread at a time.

What happens if I forget to use the lock?

If you forget to use the lock, multiple threads may access the shared resource simultaneously, leading to inconsistent or corrupted data.

Are there other types of locks I can use?

Yes, Python also provides RLock (reentrant lock), Semaphore, and Condition for different synchronization needs.
