10.Python多线程（threading）

import time
import threading
def sing(msg,a):
    while True:
        print(msg,a)
        time.sleep(1)

def dance(msg):
    while True:
        time.sleep(2)
        print(msg)

if __name__ == "__main__":
    #创建一个唱歌的线程                             args元组的形式传参
    sing_thread = threading.Thread(target =sing,args=("正在唱歌","啦啦啦"))

    #创建一个跳舞的线程                             args字典的形式传参
    dence_thread = threading.Thread(target = dance,kwargs= {"msg":"正在跳舞"})

    #start()开启线程
    sing_thread.start()
    dence_thread.start()
