python Manager and pipes 简单操作

Manager：

from multiprocessing import Process, Manager
import os

def f(d, l):
    d[1] = '1'
    d['2'] = 2
    d[0.25] = None
    l.append(os.getpid())
    print(l)


if __name__ == '__main__':
    with Manager() as manager:
        d = manager.dict()#生成一个字典，可在多个进程间共享和传递

        l = manager.list(range(5))#生成一个列表，可在多个进程间共享和传递
        print(l)
        p_list = []
        for i in range(10):
            p = Process(target=f, args=(d, l))
            p.start()
            p_list.append(p)
        for res in p_list:
            res.join()

        print(d)
        print(l)
