How does the Python collections module handle thread safety?

The Python collections module provides several data structures, but it doesn't guarantee thread safety. You need to manage synchronization yourself.

What are some thread-safe alternatives in Python?

You can use the queue.Queue class for thread-safe FIFO queues, or threading.Lock for manual synchronization.

Can you give an example of using a lock with a collection?

Sure! You can use a Lock to synchronize access to a list. Here's a simple example:

import threading

lock = threading.Lock()
my_list = []

def add_to_list(item):
    with lock:
        my_list.append(item)

Are there any built-in thread-safe collections in Python?

Yes, the queue module provides thread-safe classes like Queue, LifoQueue, and PriorityQueue.
