What are locks in Python?

Locks in Python are synchronization primitives that help manage access to shared resources in multithreading.

How do I implement a lock in my Python code?

You can use the threading module. Create a lock using lock = threading.Lock() and use lock.acquire() and lock.release().

Can you give me an example of using a lock?

Sure! Here's a simple example:

import threading

lock = threading.Lock()

def thread_function():
    lock.acquire()
    try:
        # critical section
        print('Thread is running')
    finally:
        lock.release()

What happens if I forget to release the lock?

If you forget to release the lock, it can lead to a deadlock situation where other threads are blocked indefinitely.
