Pause function in pygame mixer is not working

Question

I am currently making a GUI with Tkinter that plays music. The program is able to correctly play the songs, and I am trying to implement a pause button. This is the code I have, does anyone know why this might not be working? I know the button is linked properly since I have tried printing something out when the button is clicked, and that works. Also, there are no error messages, the audio is just not pausing.

        self.songDict = {}
        num = 1
        while True:
            if os.path.exists(str(num)+'.jpg'):
                os.remove(str(num)+'.jpg')
                num += 1

root = Tk()
root.title("MP3 Player")
root.geometry("400x400")
app = Application(root)
root.mainloop()

Answer 1

try using:

pygame.mixer.music.pause()

instead of:

pygame.mixer.pause()
