Question

Anubhav Sharma · Answer

Python’s Global Interpreter Lock (GIL): GIL is a mutex (lock) that allows only one thread to execute Python bytecode at a time.It prevents true multi-threaded CPU-bound parallelism.For I/O-bound tasks → use multithreading.For CPU-bound tasks → use multiprocessing to bypass GIL.
