The disadvantage of this solution is, that the entire file is loaded into ram before saved to disk, just something to keep in mind if using this for large files on a small system like a router with limited ram.

@tripplet so how would we fix that?

To avoid reading the whole file into memory, try passing an argument to file.read that is the number of bytes to read. See: gist.github.com/hughdbrown/c145b8385a2afa6570e2

@hughdbrown I found your script useful, but have one question: can I use the file for post-processing? suppose I download a jpg file that I want to process with OpenCV, can I use the 'data' variable to keep working? or do I have to read it again from the downloaded file?

Use shutil.copyfileobj(mp3file, output) instead.
