Python--多進程

# 想利用多核cpu,那麼就使用多進程import multiprocessingimport timeimport threadingdef run2():    print('這是多線程啓動的')def run():    time.sleep(2)    print('多進程')    for j in range(5):        t = threading.Thread(target=run2)        t.start()if __name__ == '__main__':    for i in range(5):        p = multiprocessing.Process(target=run)        p.start()
