What is thread-local storage in Python?

Thread-local storage (TLS) allows data to be stored in a way that is unique to each thread. In Python, this can be achieved using the threading.local() class.

How do I implement thread-local storage in my Python application?

You can implement it by creating an instance of threading.local() and then assigning attributes to it. Each thread will have its own separate instance of these attributes.

Can you give me an example of using thread-local storage?

Sure! Here's a simple example:

import threading

thread_local_data = threading.local()

def process_data():
    thread_local_data.value = threading.current_thread().name
    print(f'Thread name: {thread_local_data.value}')

thread1 = threading.Thread(target=process_data)
thread2 = threading.Thread(target=process_data)

thread1.start()
thread2.start()
thread1.join()
thread2.join()
