Multithreading vs Multiprocessing in Python: When to Use Each?
- Multithreading in Python involves running multiple threads within a single process. Threads share the same memory space, making them lightweight and fast to create.
- Multithreading is best for I/O-bound tasks like waiting for network responses or reading files.
- Multiprocessing in Python involves spawning multiple independent processes, each with its own memory space and Python interpreter. It bypasses the Global Interpreter Lock (GIL) and allows true parallelism for CPU-bound tasks.
- Multiprocessing is best for CPU-bound tasks like mathematical computations or image processing.
