Learn how to create variables in python, assign string and numeric values, and print results, while understanding memory references, data types, and the importance of unique variable names.

Explore variable naming conventions in Python and Django, following lowercase with underscores for readability, uppercase constants, and global versus local scope, aligned with pep8 style.

Learn how to create and name Django view variables, pass them as context to templates, and render dynamic data in the browser through the request-response cycle.

Discover python built-in functions and how they simplify coding, with examples of print and len, plus tips to avoid naming conflicts with existing functions.

Use the Python built-in print function as a Django diagnostic tool to inspect data from a database and explore request data and URL information during development.

Explore Python's built-in data types, including strings, integers, floats, booleans, dictionaries, sets, and sequences, and learn how to convert values between types to support required operations.

Explore casting in Python to define a specific data type on a variable using str, int, float, and bool, and verify results with the type function.

Explore how Django model data types map to field types, validate input, and store data in databases using character, integer, date, email, and JSON fields with auto fields.

Define a Django model as a blueprint for a database table and map fields like name, age, and mobile to a class. Learn about primary keys and the string method.

Create and apply migrations for Django models to update the SQLite database schema, building new tables like customer and applying changes with makemigrations and migrate.

Create a new Django admin user, run the server, and access the admin page at /admin to manage and inspect your database table through the admin site.

Register a Django model with the admin site to manage data: import the model, register it in admin.py, run the server, log in at /admin, and add or edit customers.

Register a Django model in the admin site, run the server, and add data through the interface. Learn how the string representation and data types affect display and validation.

Explore the Python list data type, a mutable container for storing multiple values in a single variable using square brackets, which is ordered and dynamic with indexing.

Order elements in a Python list using sort and sorted, with ascending and descending options. Explain in-place versus copy behavior and how sorting influences data displayed from databases in Django.
