本文實(shí)例講述了Python實(shí)現(xiàn)多進(jìn)程共享數(shù)據(jù)的方法。分享給大家供大家參考，具體如下：
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('這是進(jìn)程{} {}'.format(number, a_list)) print('這是進(jìn)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')輸出：

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('這是進(jìn)程{} {}'.format(number, a_list)) print('這是進(jìn)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')輸出：
這是進(jìn)程0 [0, 0]這是進(jìn)程0 [0, 0, 1]這是進(jìn)程0 [0, 0, 1, 2]這是進(jìn)程0 [0, 0, 1, 2, 3]這是進(jìn)程0 [0, 0, 1, 2, 3, 4]這是進(jìn)程1 [0, 0, 1, 2, 3, 4, 5]這是進(jìn)程0 [0, 0, 1, 2, 3, 4, 5, 1]這是進(jìn)程1 [0, 0, 1, 2, 3, 4, 5, 1, 6]這是進(jìn)程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2]這是進(jìn)程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3]這是進(jìn)程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4]這是進(jìn)程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5]這是進(jìn)程0 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6]這是進(jìn)程0 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7]這是進(jìn)程0 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8]這是進(jìn)程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8, 9]這是進(jìn)程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8, 9, 7]這是進(jìn)程0 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8, 9, 7, 8]這是進(jìn)程0 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8, 9, 7, 8]這是進(jìn)程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8, 9, 7, 8]這是進(jìn)程1 [0, 0, 1, 2, 3, 4, 5, 1, 6, 2, 3, 4, 5, 6, 7, 8, 9, 7, 8, 9]這是進(jìn)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
