python多线程，两个while True

python多线程实现同时执行两个while循环 如果想同时执行两个while True循环，可以使用多线程threading来实现。 python串口通信与tkinter gui界面：https://blog.csdn.net/qq_40889820/article/details/100150253 完整代码

from time import sleep, ctime import threading def muisc(func): while True: print ('Start playing： %s! %s' %(func,ctime())) sleep(2) def move(func): while True: print ('Start playing： %s! %s' %(func,ctime())) sleep(5) def player(name): r = name.split('.')[1] if r == 'mp3': muisc(name) else: if r == 'mp4': move(name) else: print ('error: The format is not recognized!') list = ['爱情买卖.mp3','阿凡达.mp4'] threads = [] files = range(len(list)) #创建线程 for i in files: t = threading.Thread(target=player,args=(list[i],)) threads.append(t) if __name__ == '__main__': #启动线程 for i in files: threads[i].start() for i in files: threads[i].join() #主线程 print ('end:%s' %ctime())
