How to convert mp4 to mp3 using python [closed]

Question

How can I convert a mp4 or mpeg4 file to mp3 using python?

I have looked at several libraries without success.

This sounds like task for MoviePy. After you install it (installation howto) it could be used following way:

import os
from moviepy.editor import *
video = VideoFileClip(os.path.join("path","to","movie.mp4"))
video.audio.write_audiofile(os.path.join("path","to","movie_sound.mp3"))

Just replace "path","to","movie.mp4" and "path","to","movie_sound.mp3" according to your needs.

EDIT: To avoid the KeyError: 'video_fps', do ensure that you aren't inputting any video which does not contain any visual content.
