Python fork(): passing data from child to parent

Question

I have a main Python process, and a bunch or workers created by the main process using os.fork().

I need to pass large and fairly involved data structures from the worke

Answer 1

multiprocessing's queue implementation works.

q = multiprocessing.Queue()
if (os.fork() == 0):
    print(q.get())
else:
    q.put(5)
# outputs: 5
