Compile a python script automatically when website is opened

Is there any way to compile a program automatically when opening a web page. I have a website that mainly runs off of js. In order for the Spotify playlist that shows up in a pop up window to work, my Spotify_server.py has to be run first. I know I could just open the server before I present the app, but is there anyway I could make it run so that the Spotify_server.py script compiles automatically when I open the index.html file?
