What are some examples of multithreading in Python?

Multithreading in Python allows concurrent execution of code. A common example is using the threading module to run tasks simultaneously.

Can you show me a simple code 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 happens if I don't use join()?

If you don't use join(), the main program may finish executing before the thread completes, leading to incomplete output.

Are there any limitations to multithreading in Python?

Yes, due to the Global Interpreter Lock (GIL), Python threads may not achieve true parallelism, especially in CPU-bound tasks.
