Running files using random - ebolisa - Sep-09-2019
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
#!/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:
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.
