python 异步非阻塞的简单实现

利用@注解函数名（装饰器），可实现简单的异步非阻塞。上代码：

# -*- coding:utf-8 -*-
import time
from threading import Thread


class Async:
    """
    使用装饰器实现多线程的异步非阻塞
    """

    def start_async(*args):
        fun = args[0]

        def start_thread(*args, **kwargs):
            """
            启动线程（内部方法）
            """
            t = Thread(target=fun, args=args, kwargs=kwargs)
            t.start()

        return start_thread

    @start_async
    def new_thread(*args):
        while 1:
            print("这里是阻塞的死循环...")
            time.sleep(1)


if __name__ == '__main__':
    # 启动异步线程
    Async().new_thread()
    # 主线程
    t0 = time.time()
    while time.time() - t0 < 1000:
        time.sleep(3)
        print("主进程...")

运行结果：
