Articles, Tutorials and Talks

This tutorial demonstrates how to use the Python 'Anvil' framework to make modern web apps that run on every common platform (Windows, Mac, Linux, Android, iOS, Chromebook, etc.), in the easiest, most productive way possible. You'll learn how to create several dozen useful apps with Anvil, using nothing but Python code, in just a few hours. You don't need to have any previous experience to complete this tutorial.

Materialized views can be very useful for creating reports that will be used repeatedly. They cut down on query times because the query has already been made, and the view has been written to the disk. In this video, Nafiul Islam demonstrates how to create materialized views, explains the benefits of using them, and shows how to integrate them into Django ORM.

My journey creating a dataclass converter by using abstract syntax trees, match-case, the dedent utility and more. You may learn something new along the way.

Flask and Quart both utilize Werkzeug's HTTP router to route request paths to the relevant function. With the upcoming 2.2 release of Werkzeug this router will be significantly faster, with up to a factor of 5 seen in testing. This speedup increases with the size of the routing table and so you are likely to see further increases in your production applications. 

We take a visual approach to gain an intuition behind text embeddings, what use cases they are good for, and how they can be customized using finetuning.

Complete Python tutorial to create supervised learning AI systems for semantic segmentation of unstructured 3D LiDAR point cloud data.

Prior to Django 4.0 forms were rendered by string concatenation. A number of 3rd party packages allowed for forms to be rendered as templates e.g. floppy forms, crispy-forms. Django 4.0 introduced the capability to render forms using the template engine. This allowed the form template to be set per form class or per instance if a template name is provided when calling render().

Even though you don't see type hints all that often in Python code, and they'll probably never become obligatory, I still think you should use them. Here are 5 reasons why.
