Flasks in Python

Flask is a micro web framework written in Python.

A web framework is a software framework that is designed to support the development of web applications and deploy them.

Flask is classified as a micro-framework because it does not require particular tools or libraries.

The ‘micro’ in micro-framework means Flask aims to keep the core simple but extensible.

Flask won’t make any decision for you such as what database to use; the decisions that it makes are easy to change.

Flask allows us to build a web application eg, web pages, a blog, Wiki, etc.

Pros and Cons of a Micro-Framework-

• Light framework.
• Little dependency to update and watch for security bugs.
• More work done by the user.
• If work not to be done by the user, then increase the list of dependencies by adding plug-ins.

Flask Supported Dependencies-

1. Werkzeug — WSGI utility library — The Web Server Gateway Interface (WSGI) is a simple calling convention for web servers to forward requests to web applications or frameworks written in the Python.
2. Jinja2 — Template engine.
