I'm looking for a simple example that streams MP3 over http.
I know how to Google, and even to use GitHub search but while I found several examples for using python I
didn't find anything using twisted.
Any help would be appreciated
You don't really need to do anything special. If you have a .mp3 file on your filesystem, a static.File (the thing you get from twistd web --path ...) can "stream" the mp3 just fine.
If you don't just mean serving up a file without chewing up OS resources like PIDs or thread stacks, you'll have to be more specific about what you mean by "streaming MP3".
