Python instances of inter-process communication usage

This example describes the Python interprocess communication usage. Share to everyone for your reference. Specific as follows:

#!/usr/bin/env python#-*-coding=utf-8-*-import multiprocessingdef counsumer (input_q): While  True:    item = Input_q.get ()    #处理项目    Print item #此处替换为有用的工作    #发出信号通知任务完成    Input_q.task_done () def producer (sequence, OUTPUT_Q): For  item in sequence:    #将项目放入队列    output_q.put (item) #建立进程if __name__ = = ' __main__ ':  q = Multiprocessing. Joinablequeue () #创建可连接的共享进程队列  cons_q = multiprocessing. Process (target=counsumer,args= (q,))  Cons_q.daemon = True  cons_q.start ()  sequence = [1,2,3,4]  Producer (SEQUENCE,Q)  q.join ()  print ' success '
