What are the main advantages of using Django in web application development?

Django is a high-level web framework for Python that offers several advantages:

• Rapid development: Django comes with a large set of ready-to-use components (authentication, admin, ORM), which speeds up application development.
• Clean architecture: It follows the DRY (Don't Repeat Yourself) principle, reducing code duplication.
• Security: Built-in mechanisms protect against common vulnerabilities (XSS, CSRF, SQL injection).
• Scalability: Easily extendable as load increases.
• Large community and documentation: Extensive knowledge base and many third-party packages.

Example of a simple view in Django:

from django.http import HttpResponse

def hello(request):
    return HttpResponse("Hello, world!")
