How can I use spotDL inside python?

Question

I know that spotDL is a command-line application built in python, but is there any way to use it inside a script?

Answer 1

Short answer: Yes

Long answer: Yes

You see, spotDL is a command-line application, and requires the use of command-line arguments. In python, there isn't a way (as of I know) to set these arguments.

I believe you are asking on how to use an import and use a function directly such as spotdl.download(spotifylink), however, the application is only designed for command-line use. So lets do that then!

How?

Well, we can use the subprocess module to launch up spotdl via the python executable.

import subprocess
import sys # for sys.executable (The file path of the currently using python)
from spotdl import __main__ as spotdl # To get the location of spotdl

spotifylink = "Whatever you want to download"
subprocess.check_call([sys.executable, spotdl.__file__, spotifylink])

Edit: There is a better way to do it (Requires pytube)

from spotdl import __main__ as start # To initialize
from spotdl.search.songObj import SongObj
from pytube import YouTube

spotifylink = "Whatever you want to download"
song = SongObj.from_url(spotifylink)
url = song.get_youtube_link() # Yay you have a youtube link!
yt = YouTube(url)
yts = yt.steams.get_audio_only()
fname = yts.download()

print(f"Downloaded to {fname}")
