Django Function-Based View
A Function-Based View is created with the help of a python function that is called a view function and It returns an HTTP response on an HTTP request.
An Http Response is an object that is represented as httpRequest and passed as first arguments of the view function.
An HTTP response is also an object that is represented as HttpResponse and It can accept HTML, XML documents, text, images, video, files, & more
A Function based is also known with other alternative names like view or view function of an app.
A view function is created in views.py file of a Django app with the help of this syntax –
def functionName(request): return HttpResponse("Write your Contenr")
def welcome(request): return HttpResponse("<h1>Welcome to Django Tutorials</h1>")
Single Function Based View
If you need a single view of your app then you can create a single function based view
def welcome(request): return HttpResponse("<h1>Welcome to CodingStatus</h1>"
Multiple Function Based View
If you need multiple views of your app then you can create multiple function based views
def welcome(request): return HttpResponse("<h1>Welcome to CodingStatus</h1>") def about(request): return HttpResponse("<p>Codingstatus is the best website for learning to develop the best web applications</p>")

Now, You will learn to create some function based views steb by step with an example. So, let’s start –
