Python—进程间通信

from multiprocessing import Process,Pipe import os,time # fd1只能recv,fd2只能send # fd1,fd2 = Pipe(False) # 创建一个双向管道 fd1,fd2 = Pipe() # fd1.close()def fun(name): time.sleep(1) # 子进程发送字符串到管道 fd2.send("hello "+str(name)) print(os.getppid(),"...",os.getpid()) jobs = [] for i in range(5): p = Process(target = fun,args = (i,)) jobs.append(p) p.start() # 父进程从管道接受子进程发送来的消息,发送与接受的都是字符串 for i in range(5): data = https://www.it610.com/article/fd1.recv() print(data) for i in jobs: i.join()
