What it does

Flask is a lightweight Python framework for building web applications, allowing startup founders to quickly create and deploy web services.

When to use it
  • •Building a prototype or minimum viable product (MVP) for a web application
  • •Creating a web service with a small codebase and few dependencies
  • •Developing a RESTful API for a small to medium-sized application
Ready-to-paste prompt
flask run --host=0.0.0.0 --port=5000 to run the application on all available network interfaces
Heads up: Make sure to set the `FLASK_APP` environment variable to the name of your application file (e.g. `export FLASK_APP=app.py`) before running `flask run`
