python创建线程示例

复制代码 代码如下:

import threading

from time import sleep

def test_func(id):

    for i in range(0,5):

        sleep(1)

        print('thread %d is running %d' % (id,i))

threads = []

for i in range(0,3):

    t = threading.Thread(target=test_func, args=(i,))

    threads.append(t)

for t in threads:

    t.start()

for t in threads:

    t.join()

从输出结果可以看到，3个线程是交替的执行的
