How do you deploy a flask app to production?

Deploy to Production
  1. When you want to deploy your application elsewhere, you build a distribution file.
  2. Running setup.py with Python gives you a command line tool to issue build-related commands.
  3. You can find the file in dist/flaskr-1.0.
  4. Copy this file to another machine, set up a new virtualenv, then install the file with pip .

Furthermore, can you use flask for production?

Although Flask has a built-in web server, as we all know, it's not suitable for production and needs to be put behind a real web server able to communicate with Flask through a WSGI protocol. While being an HTTP web server, Gunicorn, in turn, is an application server not suited to face the web.

Subsequently, question is, why is heroku free? Heroku offers a free plan to help you learn and get started on the platform. Heroku Buttons and Buildpacks are free, and many Heroku Add-ons also offer a free plan. Experiment easily with different technologies to discover what works best for you and your apps.

What is __ Name __ in Python?

The __name__ variable (two underscores before and after) is a special Python variable. It gets its value depending on how we execute the containing script. Sometimes you write a script with functions that might be useful in other scripts as well. In Python, you can import that script as a module in another script.
