from threading import Thread

import time

def func(n): #子线程完成的

    time.sleep(1)

    print(n)

#多线程示例

for i in range(10):

    t = Thread(target=func, args=(i,)) #func的子线程注册到主线程

    t.start()

使用面向对象的方式开启新的线程

from threading import Thread

import time

class MyThread(Thread):

    def __init__(self,arg):

        super().__init__()

        self.arg = arg

    def run(self):

        time.sleep(1)

        print(self.arg)

for i in range(10):

    t = MyThread(i)

    t.start()
