本文实例讲述了Python实现多进程共享数据的方法。分享给大家供大家参考，具体如下：

示例一：

# -*- coding:utf-8 -*-from multiprocessing import Process, Managerimport timeimport randomdef kkk(a_list, number): for i in range(10): a_list.append(i) time.sleep(random.randrange(2)) print('这是进程{} {}'.format(number, a_list)) print('这是进程{} {}'.format(number, a_list))def jjj(a_list): for i in range(2): process = Process(target=kkk, args=(a_list, i)) process.start()if __name__ == '__main__': a_list = [] process_0 = Process(target=jjj, args=(a_list,)) process_0.start() process_0.join() print(a_list) print(len(a_list)) print('it\'s ok')

输出：

这是进程0 [0]这是进程0 [0, 1]这是进程0 [0, 1, 2]这是进程0 [0, 1, 2, 3]这是进程1 [0]这是进程0 [0, 1, 2, 3, 4]这是进程1 [0, 1]这是进程0 [0, 1, 2, 3, 4, 5]这是进程1 [0, 1, 2]这是进程1 [0, 1, 2, 3]这是进程1 [0, 1, 2, 3, 4]这是进程1 [0, 1, 2, 3, 4, 5]这是进程0 [0, 1, 2, 3, 4, 5, 6]这是进程0 [0, 1, 2, 3, 4, 5, 6, 7]这是进程0 [0, 1, 2, 3, 4, 5, 6, 7, 8]这是进程1 [0, 1, 2, 3, 4, 5, 6]这是进程0 [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]这是进程0 [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]这是进程1 [0, 1, 2, 3, 4, 5, 6, 7]这是进程1 [0, 1, 2, 3, 4, 5, 6, 7, 8]这是进程1 [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]这是进程1 [0, 1, 2, 3, 4, 5, 6, 7, 8, 9][]0it's okProcess finished with exit code 0

示例二：

使用 Manager

# -*- coding:utf-8 -*-from multiprocessing import Process, Managerimport timeimport randomdef kkk(a_list, number): for i in range(10): a_list.append(i) time.sleep(random.randrange(2)) print('这是进程{} {}'.format(number, a_list)) print('这是进程{} {}'.format(number, a_list))def jjj(a_list): for i in range(2): process = Process(target=kkk, args=(a_list, i)) process.start()if __name__ == '__main__': manager = Manager() a_list = manager.list() # a_list = [] process_0 = Process(target=jjj, args=(a_list,)) process_0.start() process_0.join() print(a_list) print(len(a_list)) print('it\'s ok')

输出：

这是进程0 [0, 0]这是进程0 [0, 0, 1]这是进程0 [0, 0, 1, 2]这是进程0 [0, 0, 1, 2, 3]这是进程0 [0, 0, 1, 2, 3, 4]这是进程1 [0, 0, 1, 2, 3, 4, 5]这是进程0 [0, 0, 1, 2, 3, 4, 5, 1]这是进程1 [0, 0, 1, 2, 3, 4, 5, 1, 6]这是进程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2]这是进程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3]这是进程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4]这是进程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5]这是进程0 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6]这是进程0 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7]这是进程0 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8]这是进程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8, 9]这是进程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8, 9, 7]这是进程0 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8, 9, 7, 8]这是进程0 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8, 9, 7, 8]这是进程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8, 9, 7, 8]这是进程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8, 9, 7, 8, 9]这是进程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8, 9, 7, 8, 9][0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8, 9, 7, 8, 9]20it's okProcess finished with exit code 0
