Chapter 1: Installing Python and Django

Welcome to Django 4 for the Impatient! This book focuses on the key tasks and concepts to help you to learn and build Django applications fast. It is designed for readers who don't need all the details about Django except for concepts that you really need to know. By the end of this book, you will be confident creating your own Django projects.

So, what's Django? Django is a free, open source web framework for building modern Python web applications. Django helps you quickly build web apps by abstracting away many of the repetitive challenges involved in building a website, such as connecting to a database, handling security, enabling user authentication, creating URL routes, displaying content on a page through templates and forms, supporting multiple database backends, and setting up an admin interface.

This reduction in repetitive tasks allows developers to focus on building a web application's functionality rather than reinventing the wheel for standard web application functions.

Django is one of the most popular frameworks available and is used by established companies such as Instagram, Pinterest, Mozilla, and National Geographic
