How do I implement locks in my application?

To implement locks, you can use mutexes or semaphores depending on your needs. What programming language are you using?

I'm using Python. Can you give me an example?

Sure! In Python, you can use the threading module. Here's a simple example:

import threading

lock = threading.Lock()

def thread_safe_function():
    with lock:
        # critical section of code
        print('Lock acquired!')

This ensures that only one thread can execute the critical section at a time.

What if I need to implement it in a web application?

For web applications, you might want to use distributed locks, especially if you're using multiple servers. Libraries like Redis can help with that. Would you like to know more about that?
