Running files using random

[ebolisa]

Hi,

The following code plays a mp3 file from a folder randomly. After few days running, it stops but I just cannot find the problem/cause. What king of checks should I add into the code to trap the culprit line?

TIA

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

#!/usr/bin/python3   from __future__ import print_function import random, os import pygame import logging   #music files path path = "/media/usb/"   #get music files songs = os.listdir(path)   #filter mp3 files songs = [fi for fi in songs if fi.endswith(".mp3")]   pygame.init() pygame.mixer.init() #print(pygame.mixer.get_init())   def play_songs():     try:         #pygame.mixer.music.set_volume(0.50)         filename = random.choice(songs)         #print('playing now {}'.format(filename))         pygame.mixer.music.load(path + filename)         pygame.mixer.music.play()         while pygame.mixer.music.get_busy():             pygame.time.Clock().tick(10)     except ValueError:         logging.exception("msg from music.py: " +format(ValueError))         print('Excemption: {}', format(ValueError))   if __name__ == '__main__':     while True:         play_songs()

Just define a main function:

1 2 3 4 5 6 7 8

import sys   def main():     while True:         play_songs()   if __name__ == '__main__':     sys.exit(main())

That way you get the return code of the script.

So, if I understand the code right, it loops regardeless of the error (if any)?
Thank you.

This is an addition to your code. A wrapper function for the last if block. When it happens to stop again you should see the exit code of the program and you can make assumptions about the reason.

I see, unfortunatelly, the board is not connected to a monitor. I can only see the errors in the syslog.

You can just redirect the output to a file and then you can read it.
