I have multiple (between 40 and 50) MP3 files that I'd like to concatenate into one file. What's the best way to do this in Python?
Use fileinput
module to loop through each line of each file and write it to an output file? Outsource to windows copy
command?
Putting the bytes in those files together is easy... however I am not sure if that will cause a continuous play - I think it might if the files are using the same bitrate, but I'm not sure.
from glob import iglob
import shutil
import os
PATH = r'C:\music'
destination = open('everything.mp3', 'wb')
for filename in iglob(os.path.join(PATH, '*.mp3')):
shutil.copyfileobj(open(filename, 'rb'), destination)
destination.close()
That will create a single "everything.mp3" file with all bytes of all mp3 files in C:\music concatenated together.
If you want to pass the names of the files in command line, you can use sys.argv[1:]
instead of iglob(...)
, etc.
