# Python Development Guide
## Django Framework
Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design.
### Models
Django models define the data structure and provide database abstraction.
```python
from django.db import models
class Article(models.Model):
title = models.CharField(max_length=200)
content = models.TextField()
created_at = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.title
```
### Views
Views handle the request/response cycle and contain the business logic.
```python
from django.shortcuts import render, get_object_or_404
from django.http import HttpResponse
from .models import Article
def article_list(request):
articles = Article.objects.all()
return render(request, 'articles/list.html', {'articles': articles})
def article_detail(request, pk):
article = get_object_or_404(Article, pk=pk)
return render(request, 'articles/detail.html', {'article': article})
```
## Database Operations
- Use Django ORM for database operations
- Create migrations for schema changes
- Implement proper indexing for performance
- Consider database-level constraints
