Python多进程与多线程

多进程更适合CPU密集型任务，而多线程更适合IO密集型任务。

多进程

multiprocessing模块

import multiprocessing

def my_function(arg1, arg2):
    print("Do something with arguments{},{}".format(arg1, arg2))

if __name__ == '__main__':
    p = multiprocessing.Process(target=my_function, args=("arg1", "arg2"))
    p.start()
    p.join()

多线程

使用threading模块创建线程

import threading

def my_function(arg1, arg2):
    print("Do something with arguments{},{}".format(arg1, arg2))

if __name__ == '__main__':
    t = threading.Thread(target=my_function, args=("arg1", "arg2"))
    t.start()
    t.join()
