What are some examples of synchronization in code?

Synchronization in code refers to techniques that ensure that multiple threads or processes can operate safely without conflicts. Examples include mutexes, semaphores, and monitors.

Can you explain how a mutex works?

A mutex, or mutual exclusion, is a locking mechanism that prevents multiple threads from accessing a shared resource simultaneously. When a thread locks a mutex, other threads must wait until it is unlocked.

What about semaphores? How do they differ from mutexes?

Semaphores are signaling mechanisms that can allow multiple threads to access a limited number of resources. Unlike mutexes, which allow only one thread at a time, semaphores can permit a specified number of threads to access a resource concurrently.

Can you give a code example of using a mutex?

Sure! Here's a simple example in Python using the threading module:

import threading

mutex = threading.Lock()

def thread_function():
    with mutex:
        # Critical section of code
        print('Thread is accessing the shared resource')
