Django's request-response lifecycle involves processing a web request, routing it, and returning an appropriate response.

• 1. Request Initiation: A user sends an HTTP request to the server.

• 2. URL Routing: Django uses URLconf to match the request to a view function.

• 3. View Processing: The view processes the request, interacts with models, and prepares a response.

• 4. Template Rendering: If needed, the view renders a templat...read more

Lists are mutable collections, while tuples are immutable, offering different use cases in Python programming.

• Lists can be modified: Example - list.append(4) adds an element.

• Tuples cannot be modified: Example - tuple[0] = 1 raises an error.

• Lists use more memory due to their dynamic nature.

• Tuples are faster for iteration and access due to their immutability.

• Lists are defined with square brackets: my_list = [1, 2, 3].

• Tup...read more

Django simplifies form validation with built-in classes and custom methods for robust data handling.

• Use forms.Form for basic forms and forms.ModelForm for model-based forms.
