what is pip install waitress and production wsgi. When i run my code repl advise me to use a production wsgi instead. I don't know what that is.
Can someone please explain it to me?
if you do app.run(debug=True, host="0.0.0.0") it will show you a window which has the preview of your (Whatever you are hosting) and you can click on open a new tab which will take you to a tab with that page open, you can use that url anywhere to access that page. I have not used WSGI, I only used repl to host an API for my friends for a few hours but I think it should work with WSGI as well.
WSGI, or Web Server Gateway Interface, is a way for servers to interact with clients. Are you making a server?
