URLs & views

A view is request → response, same as Flask

Strip away the file spray and Django's core idea is identical to Flask's: a Python function takes a request and returns a response. Django calls that function a view, and it lives in walks/views.py instead of decorated inline in app.py.

The difference is registration. Flask decorates the function directly: @app.route("/walkers"). Django keeps views and routing in two separate files — the view is just a plain function, and a separate urls.py maps a path to it.
