What is threading in Python and how can I use it?

Threading in Python allows you to run multiple threads (smaller units of a process) concurrently, which can improve performance for I/O-bound tasks.

Can you show me a simple example of using threading?

Sure! Here's a basic example:

import threading

def print_numbers():
    for i in range(5):
        print(i)

thread = threading.Thread(target=print_numbers)
thread.start()
thread.join()

What does thread.join() do?

thread.join() makes the main program wait until the thread has finished executing before continuing.

Are there any potential issues with using threading?

Yes, threading can lead to issues like race conditions and deadlocks if not managed properly. It's important to use locks when accessing shared resources.
