How can I implement my own thread-safe collection in programming?

What is a thread-safe collection and why do I need one?

A thread-safe collection is designed to handle concurrent access by multiple threads without causing data corruption. It's essential in multi-threaded applications to ensure data integrity.

How can I implement my own thread-safe collection in Python?

You can use threading locks to control access to your collection. For example, you can create a class that wraps a list and uses a lock to synchronize access.

Can you show me a simple code example?

Sure! Here's a basic example:

import threading

class ThreadSafeList:
    def __init__(self):
        self.lock = threading.Lock()
        self.items = []

    def add(self, item):
        with self.lock:
            self.items.append(item)

    def get(self, index):
        with self.lock:
            return self.items[index]

What are some common pitfalls when creating thread-safe collections?

Common pitfalls include deadlocks, performance issues due to excessive locking, and not properly handling exceptions within locked sections.
