What are some examples of multi-threading in Python?

Multi-threading in Python allows concurrent execution of code. A common example is using the threading module to run tasks in parallel.

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 multi-threading in Python?

Yes, due to the Global Interpreter Lock (GIL), Python threads are not truly concurrent in CPU-bound tasks, but they work well for I/O-bound tasks.
