edit: Ended up using the built-in render_template function to display output using Jinja2 markup, which proved to be a perfect solution.

Flask is a process and will keep running forever, unless it encounters a fatal exception.
Typically, a web server process exiting would be a terrible design.
Try this for the functionality you want: How to stop flask application without using ctrl-c

Thanks for your input, John. However, I wasn't able to grasp how I could use this in the way I want it to work. What I'm trying to build is a frontend for multiple users, and I'm not sure how I would code the shutdown function into the application so that it'd kill the process after a user gets their scraped data. Sorry if I'm missing something. edit: Basically, I want it to scrape, print the data on browser and then stop. For multiple users.

Add in that shutdown_server function and call it from your process.

Added the following after the return statement, still no go.
requests.post('http://localhost:5000/done') @app.route('/done', methods=['POST']) def done(): func = request.environ.get('werkzeug.server.shutdown') if func is None: raise RuntimeError('Not running with the Werkzeug Server') func()John
Try installing werkzeug. pip install werkzeug

I have tried it with this snippet: codeshare.io/EgYKr It works, potential installation issue- which version flask are you running?
