This is the simplest way to define views in Django. Each view is a Python function that takes a web request and returns a web response. Function Based Views (FBVs) are another way to define views in Django. [[Class based views]] are based on Python classes. FBVs, on the other hand, are based on Python functions. In FBVs, you define a function for each view, which takes a web request and returns a web response. This is the traditional way of defining views in Django. For example: ```python from django.http import HttpResponse def my_view(request): return HttpResponse('Hello, World!') ``` CBVs were introduced to solve the problem of code reusability and to keep the code DRY (Don't Repeat Yourself). With CBVs, you can create views by extending the built-in generic views or creating your own mixin classes, which can then be reused across different views or projects. FBVs can be easier to understand for beginners or for simpler views, while CBVs can be more organized and efficient for larger, more complex applications. Both FBVs and CBVs have their pros and cons, and Django allows you to use both in your application. You can choose the one that fits your needs and coding style better.
