Python inter-process communication usage example

This article mainly introduces the usage of Python inter-process communication, and involves the skills related to Python operating processes through the multiprocessing module. If you need it, refer to the following example to describe the usage of Python inter-process communication. Share it with you for your reference. The details are as follows:

#! /Usr/bin/env python #-*-coding = UTF-8-*-import multiprocessingdef counsumer (input_q): while True: item = input_q.get () # processing project print item # replace this with useful work # sending a signal to notify the task to complete input_q.task_done () def producer (sequence, output_q): for item in sequence: # Put the project into the queue output_q.put (item) # create the process if _ name _ = '_ main _': q = multiprocessing. joinableQueue () # create a connectable shared process queue cons_q = multiprocessing. process (target = counsumer, args = (q,) cons_q.daemon = True cons_q.start () sequence = [1, 2, 4] producer (sequence, q) q. join () print 'success'

I hope this article will help you with Python programming.
