If you want to call python from D, you should be able to install 
pyd with dub. Depending on your python setup, it should Just 
Work. If python is set up weird (ubuntu), you will need to 
generate some custom dub config and insert it in your dub.json. 
look for generate_dub_config.py on github for the generation 
part. or install pyd with pip and run python -m 
pyd.generate_dub_config

after that, you should be good to go. some example usage off the 
top of my head that probably doesn't compile:

py_init();
InterpContext context = new InterpContext();
context.pystmts(`
   from mutagen.flac import FLAC
   audio = FLAC("example.flac")
   audio["title"] = "An example"
`);
auto audio = context.audio;
audio.pprint();
audio.save();
