If it makes it easier to understand and adapt, the non-functional
unwinding of it is
subdir = './Playlist1'
mp3 = []
for f in os.listdir(subdir):
if f.lower().endswith('.mp3'):
path = os.path.join(subdir, f)
mp3.append(path)
mp3.sort()
Cheers, Ralph.

Hi Terry,

Just about to be AFK, but this might help.
$ find
.
./foo
./foo/bar
$ python -c 'import os; print(os.listdir("foo"))'
['bar']
$
You get given bar but it's foo/bar to open it from the higher level.
Cheers, Ralph.

Re: [Dorset] Ending Playback in mpg321 from Within Python
Terry
You need to add the directory prefix to the result of os.listdir().
So if you do os.listdir('foo') it will return ['bar', 'jam']. When you pass
these to mpg321 you want the directory name prefixed ie ['foo/bar',
'foo/jam'].
So try this:
subdir = './Playlist1'
mp3_files = sorted(os.path.join(subdir, x) for x in filter(lambda f:
f.lower().endswith(".mp3"), os.listdir(subdir)))
Best wishes
Will

Will,
The code you gave me a month or two back works beautifully, except I want
to have various Playlists in various directories whilst also playing the
chimes using a separate function. In other words, the chimes are in another
directory, so I really want to stay at the top-level directory and play the
files in various sub-directories. Your code, as it stands, relies on the MP3
files being in the current directory.
Not a problem I thought (naively); I'll just substitute the required directory
into the relevant line and bobs-your-uncle! So your:
mp3_files = sorted(filter(lambda f: f.lower().endswith(".mp3"),
os.listdir('.')))
became:
mp3_files = sorted(filter(lambda f: f.lower().endswith(".mp3"), os.listdir('./
Playlist1')))
The problem is that the code clearly enters the directory and prints the name
of the files, but it doesn't play anything and finishes the loop in about half
a
second! What am I missing?
