What is the scope of use of Pyramid framework?

The Pyramid framework is a Python-based web development framework that provides a concise, flexible and scalable way to build efficient web applications. The design philosophy of the Pyramid framework is to "make as few decisions as possible", which means that it reduces the framework's restrictions on developers as much as possible so that developers can develop according to their own needs and preferences.

So, what application scenarios is the Pyramid framework suitable for? The following are several common application scenarios and corresponding code examples:

1. API development
   The Pyramid framework is very suitable for building API interfaces because it provides a high degree of flexibility and customizability . The following is a simple API interface example:

from pyramid.config import Configurator
from pyramid.view import view_config

@view_config(route_name='hello', renderer='json')
def hello(request):
    return {'message': 'Hello, world!'}

if __name__ == '__main__':
    config = Configurator()
    config.add_route('hello', '/')
    config.scan()
    app = config.make_wsgi_app()
    serve(app, host='0.0.0.0', port=8080)

2. Responsive Web Application
   The Pyramid framework uses a template engine to generate dynamic HTML pages, so it is very suitable for building responsive Web applications. The following is an example using the Jinja2 template engine:

from pyramid.config import Configurator
from pyramid.view import view_config
from pyramid_jinja2 import renderer_factory

@view_config(route_name='home', renderer='templates/home.jinja2')
def home(request):
    return {'title': 'Home', 'content': 'Welcome to the home page!'}

if __name__ == '__main__':
    config = Configurator()
    config.add_route('home', '/')
    config.add_renderer('.jinja2', renderer_factory)
    config.scan()
    app = config.make_wsgi_app()
    serve(app, host='0.0.0.0', port=8080)

3. Authentication and Authorization
   The Pyramid framework provides identity authentication and authorization functions, allowing developers to easily integrate user login , permission management and other functions. The following is an example of using the authentication and authorization mechanism that comes with the Pyramid framework:

from pyramid.authentication import AuthTktAuthenticationPolicy
from pyramid.authorization import ACLAuthorizationPolicy
from pyramid.config import Configurator
from pyramid.view import view_config
from pyramid.security import Allow, Authenticated

class Root:
    def __init__(self, request):
        pass

@view_config(route_name='home', renderer='templates/home.jinja2', permission='view')
def home(request):
    return {'title': 'Home', 'content': 'Welcome to the home page!'}

if __name__ == '__main__':
    authn_policy = AuthTktAuthenticationPolicy('secret')
    authz_policy = ACLAuthorizationPolicy()
    config = Configurator(authentication_policy=authn_policy, authorization_policy=authz_policy, root_factory=Root)
    config.add_route('home', '/')
    config.scan()
    app = config.make_wsgi_app()
    serve(app, host='0.0.0.0', port=8080)

Summary:
The Pyramid framework is suitable for a variety of application scenarios, whether it is building API interfaces, responsive Whether it is web applications or implementing identity authentication and authorization, Pyramid provides flexible and powerful functions to meet the needs of developers. I hope the above examples can help readers better understand the application scenarios of the Pyramid framework.
