Python Django Introduction

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Built by experienced developers, it takes care of much of the hassle of Web development, so you can focus on writing your app without needing to reinvent the wheel. It’s free and open source.

Pre-readiness setup before starting Django web development

1) First, install Python latest version
    Python Installation
2) Installing Virtual Environment for development
    Windows:
    >pip install vertualenvwrapper-win
    Linux:
    >pip install vertualenvwrapper
3) Creating virtual environment
    >mkvertualenv pyvirtualenv1
4) Switching to virtual environmment
    >workon pyvirtualenv1
5) Install Django into this virtual environment using Python Package Manager(pip)
    >pip install django
6) Creating a Django application using utility

    Open terminal for your project and run below command
    >python .\manage.py runserver

10)Browse your application!!

Once Server is started  successfully and some piece of migration we need to do access the admin and so on

Console Log: You have 17 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, content types, sessions.

Run 'python manage.py migrate' to apply them.

Run the below command to apply this migration. Django uses the sqlite3 database by default so all the migration-related operations happen with these databases.

Note: If you have decided to use some other databases so that migration can be done on your other databases as well. Follow the below steps:
