Learn PYRAMID-REST with Real Code Examples

Updated Nov 27, 2025

Explain

Pyramid-REST leverages Pyramid’s traversal or URL dispatch routing to create RESTful endpoints.

Supports content negotiation, request/response serialization, and validation.

Highly configurable and minimalistic, allowing developers to add only needed components.

Integrates easily with ORMs like SQLAlchemy and authentication/authorization libraries.

Ideal for building modular APIs and microservices with Python.

from pyramid.response import Response
from wsgiref.simple_server import make_server
import json

todos = []

def list_todos(request):
    return Response(json.dumps(todos), content_type='application/json')

def add_todo(request):
    data = request.json_body
    todos.append(data)
    return Response(json.dumps(data), content_type='application/json', status=201)

if __name__ == '__main__':
    with Configurator() as config:
        config.add_route('list_todos', '/todos')
        config.add_view(list_todos, route_name='list_todos', request_method='GET')
        config.add_route('add_todo', '/todos')
        config.add_view(add_todo, route_name='add_todo', request_method='POST')
