Is it possible to implement multithreading in Python and how is it done?

Yes, multithreading can be implemented in Python, but with some limitations due to the GIL (Global Interpreter Lock), which prevents multiple threads from executing Python bytecode simultaneously. However, multithreading is useful for I/O-bound tasks, such as network requests or file operations.

To create threads in Python, the threading module is used:

import threading

def worker():
    print("Thread is running")

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

For true parallelism in compute-intensive tasks, it is better to use the multiprocessing module, which spawns processes to bypass the GIL limitation.
