How do I use the threading module in Python?

The threading module in Python allows you to run multiple threads (tasks, function calls) at once. You can create a thread by instantiating the Thread class and passing a target function.

Can you show me a simple example?

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?

The thread.join() method blocks the calling thread until the thread whose join() method is called is terminated. It ensures that the main program waits for the thread to finish.

Are there any common pitfalls when using threading?

Yes, some common pitfalls include race conditions, deadlocks, and not properly managing shared resources. It's important to use locks or other synchronization methods to avoid these issues.
