New to Heroku - "No such type as web"

Question

I'm trying to deploy my first app using Python/Flask on Heroku. I don't really know what I'm doing and am just following the tutorial at https://devcenter.heroku.com/articles/python#prerequisites. When I type the command heroku ps:scale web=1 I'm getting the error message "No such type as web". My Procfile says web: python scrabble_cheater.py, which I believe is correct. Here's the log of my terminal:

(venv)jason-olsens-macbook-pro:scrabble paulnichols$ heroku status

Any help is greatly appreciated!

Procfile was saved with a .txt extension by mistake--once I removed the extension it worked.
