开启线程

1、如何开启线程？类似开启进程一样

方式一：

from threading import Thread
import random
import time
def piao(name):
    print("%s piaoing" % name)
    time.sleep(random.randrange(1,5))
    print("%s piao end" % name)
if __name__ =="__main__":
    t=Thread(target=piao,args=("ya",))
    t.start()
    print("The main thread is end.")

方式二：

import time
import random
from threading import Thread
class MyThread(Thread):
    def __init__(self,name):
        super().__init__()
        self.name=name
    def run(self):
        print("%s piaoing" % self.name)
        time.sleep(random.randrange(1,5))
        print("%s pia end" % self.name)
if __name__=="__main__":
    p=MyThread("Test MyThread")
    p.start()
    print("The main thread is done.")
