Requirements

First, you need the following programs available on your system:

python3
pip
venv

It all should be provided with a python package in your operating system.

Starting virtual environment

To avoid polluting the global scope with package versions, we can start & use the virtual environment:

$ python3 -m venv .venv

When successful, this command creates .venv folder & produces no output.

To switch to the virtual env:

$ source .venv/bin/activate
(.venv) $

The current console will use .venv as the location for packages managed by pip.

Installing the dependency

(.venv) $ pip install pyramid

Code

I use a slightly modified example from the documentation. server.py:

from wsgiref.simple_server import make_server
from pyramid.config import Configurator
from pyramid.response import Response


def hello_world(request):
    return Response('Hello World!')


if __name__ == '__main__':
    HOST = '0.0.0.0'
    PORT = 6543

    with Configurator() as config:
        config.add_route('hello', '/')
        config.add_view(hello_world, route_name='hello')
        app = config.make_wsgi_app()
    server = make_server(HOST, PORT, app)
    print(f'Starting server at {HOST}:{PORT}') 
    server.serve_forever()

I moved HOST & PORT into variables and logged them to the console. Otherwise, the server was quietly working without notifying the user about its presence.

Running server

(.venv) $ python3 server.py
Starting server at 0.0.0.0:6543

The server works as expected:
