Quick Answer
Threads: share memory, OS-scheduled, lighter weight than processes, GIL limits CPU parallelism. Processes: separate memory spaces (communicate via queues/pipes/shared memory), true CPU parallelism, higher overhead, more isolation. Use threads for I/O-bound work (network, file), processes for CPU-bound work (computation, data processing). multiprocessing.Pool parallelizes functions across cores.
Answer
Threads share memory and suit I/O-bound tasks. Processes have separate memory and suit CPU-bound tasks. Processes bypass GIL for true parallelism.
