Lesson 3 — Views as functions

A view turns a request into a response

When someone opens a page, Django calls a view: a function that receives the request (what the browser asked for) and returns a response (what to send back, usually HTML). In real Django it looks like def home(request): return HttpResponse("Hi").

Here we simulate it: the request is a small dict and the response is a string.

def home_view(request):
    return "Hello " + request["user"]

Note: the exercise runs in your browser without Django installed, so it is a small plain-Python simulation of what Django does for you.

Why it matters: every page on a Django site is produced by a view — this is the main thing you will write.
