Concurrency control is vital for ensuring that multiple threads or processes can safely access shared resources without causing conflicts. In Python, decorators offer a straightforward way to manage concurrency and avoid potential issues.

Let’s explore how decorators can help you handle concurrency effectively through simple and practical examples.

Understanding Concurrency Control

Concurrency control involves coordinating multiple threads or processes to prevent them from interfering with each other’s operations. Without proper control mechanisms, concurrent access to shared resources can lead to data corruption or race conditions.

Implementing Thread-Safe Functions

Python’s Global Interpreter Lock (GIL) restricts the execution of multiple threads simultaneously, but it’s still essential to ensure thread safety when working with shared resources. Decorators can help achieve thread safety by synchronizing access to critical sections of code:

import threading

def synchronized(func):
lock = threading.Lock()
def…
