from multiprocessing import Pool def cube(x): return x ** 3 if __name__ == "__main__": pool = Pool(5) result = pool.map(cube, [0, 1, 2, 3])
Pool is a class which manages multiple
Workers (processes) behind the scenes and lets you, the programmer, use.
Pool(5) creates a new Pool with 5 processes, and
pool.map works just like map but it uses multiple processes (the amount defined when creating the pool).
Similar results can be achieved using
apply_async which can be found in the documentation.
