Django Introduction and Installation

What is Django?

Django is a Python-based web framework which allows you to quickly create web application without all of the installation or dependency problems that you normally will find with other frameworks. When you’re building a website, you always need a similar set of components: a way to handle user authentication (signing up, signing in, signing out), a management panel for your website, forms, a way to upload files, etc. Django gives you ready-made components to use.

Why Django?

1. It’s very easy to switch database in Django framework.

2. It has built-in admin interface which makes easy to work with it.

3. Django is fully functional framework that requires nothing else.

4. It has thousands of additional packages available.

5. It is very scalable.

• Install pip- Open command prompt and enter following command-

python -m pip install -U pip

pip install virtualenv

cd env_site

Go to Scripts directory inside env_site and activate virtual environment-
