如何在不停止程序的其余部分的情况下延迟python

Question

I am redesigning a program that basically plays sound on command. I am trying to find a way to shuffle a list of songs. I have the basic idea of what should happen but i can't seem so find a way for it to work.

I have tried stuff like 'time.sleep(1)' and '.after(miliseconds, function)'.

songlist = [["SongName","SongFileName",{length of song in miliseconds}], 
           ["SongName2","SongFileName2",{length of song in miliseconds}]]

def shuffle():
    shuffle=True
    while shuffle == True:
        song=random.choice(songlist)
        song2 =random.choice(songlist)
        while song==song2:
            song2=random.choice(songlist)
        label2.config(text=song[0])
        winsound.PlaySound(song[1], winsound.SND_ASYNC)
        window.after(song[2])

What i want to happen is for it to play random songs from the song list until the "stop" button is pressed (Stop button not shown in code)

Answer 1

Just to give you some place to start. This would give you a random song from the list.

 songlist = ['a', 'b', 'c']

 def shuffle():
      while True:
          for s in songlist:
              song=random.choice(s)

              print(song)

 if __name__ == '__main__':
      shuffle()

Answer 2

One thing you could try, is to use threads. so first import thread module:

Python2.7: from thread import start_new_thread

Python3.x: import threading

then you just call your method that you want run "parallel" to your wait function, in your case a "playSong"-method:

Python2.7: start_new_thread(playSong, ())

Python3.x:

t = threading.Thread(target=playSong)
t.start()
