What is Django and what are its main features?

Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. Its main features include an ORM (Object-Relational Mapping), an admin interface, and a robust authentication system.

To start using Django, follow these steps:

1. Install Django: pip install django
2. Create a project: django-admin startproject myproject
3. Run the development server: python manage.py runserver

For example, to create a simple model in Django, you could use:

from django.db import models

class Post(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()
