python-多任务编程-多线程-类版本

示例代码如下：

import threading
import time


class Task(threading.Thread):

    def __init__(self, food):
        super().__init__()
        self.food = food

    def run(self):
        print(self.food, "开始制作")
        time.sleep(2)
        print(self.food, "制作完成")


def main():
    food_list = ['番茄炒鸡蛋', '青椒炒牛肉']

    start_time = time.time()

    for food in food_list:
        t = Task(food)
        # 调用start才会真正创建线程, 开启线程后,会调用run方法
        t.start()

    end_time = time.time()

    print(end_time - start_time)


if __name__ == '__main__':
    main()
