How can I recover the return value of a function passed to multiprocessing.Process?

Question

In the example code below, I\'d like to recover the return value of the function worker. How can I go about doing this? Where is this value stored?

Answer 1

The pebble package has a nice abstraction leveraging multiprocessing.Pipe which makes this quite straightforward:

from pebble import concurrent

@concurrent.process
def function(arg, kwarg=0):
    return arg + kwarg

future = function(1, kwarg=1)

print(future.result())
