Unit 1: Introduction to Flask

Learn what Flask is and why it's the perfect micro web framework for Python.

What is Flask?

Understand Flask as a lightweight, flexible micro web framework for Python.

Micro Framework Python WSGI Jinja2
Flask is a micro web framework written in Python. It's classified as a microframework because it doesn't require particular tools or libraries. It has no database abstraction layer, form validation, or other components where pre-existing third-party libraries provide common functions.
