Python Textual: Build Beautiful UIs in the Terminal Textual is a Python library for building text-based user interfaces (TUIs) that support rich text, advanced layouts, and event-driven interactivity in the terminal. This tutorial showcases some of the ways you can design an appealing and engaging UI using Textual. REAL PYTHON

Binary Search as a Bidirectional Generator Python generators support a .send() method, allowing you to receive data within the generator itself. This post talks about how to use this to implement a binary search algorithm. RODRIGO GIRÃO SERRÃO

Providing Multiple Constructors in Your Python Classes In this step-by-step tutorial, you’ll learn how to provide multiple constructors in your Python classes. To this end, you’ll learn different techniques, such as checking argument types, using default argument values, writing class methods, and implementing single-dispatch methods. REAL PYTHON

Getting to Know Duck Typing in Python In this video course, you’ll learn about duck typing in Python—a type system based on an object’s behavior rather than inheritance. By taking advantage of duck typing, you can create flexible and decoupled sets of Python classes that work together or independently. REAL PYTHON course

Satellogic’s Open Satellite Feed This post explores the “Satellogic EarthView” data feed, starting with determining where the satellites are, and moving to the corresponding ground imagery. The post uses a combination of Python and DuckDB to achieve its objectives. MARK LITWINTSCHIK

The Hierarchy of Controls This article, subtitled “how to stop devs from dropping prod” takes an idea from mechanical engineering used to ensure safety around machinery and brings it to the software world to prevent accidental destruction of data. HILLEL WAYNE

Build a Dice-Rolling Application With Python In this step-by-step project, you’ll build a dice-rolling simulator app with a minimal text-based user interface using Python. The app will simulate the rolling of up to six dice. Each individual die will have six sides. REAL PYTHON

“Rules” That Terminal Programs Follow The conventions that most terminal programs follow mean that you can more easily know how to control them. Julia’s post talks about “rules” that terminal programs tend to follow, and so should yours. JULIA EVANS

Sustainable Coding: How Do I Apply It as a Cloud Engineer? Choices we make as programmers effect the amount of processing power required in production and ultimately that has a carbon cost. Ed’s post talks about how he thinks about this larger picture. ED CREWE

Font Ligatures for Your Code Editor and Terminal A font ligature combines two characters into a single rendering, allowing “>=” to look like a single symbol. This article shows you how you can do this with common terminals and editors. MIGUEL GRINBERG

Python Discord 2024 Survey Report The Python Discord server does an annual survey. This page is a giant notebook showing the results for the last four years along with the code that generates the corresponding graphs. PYTHON DISCORD

The Boolean Trap Often when using a Boolean in an API you are making the API harder to understand. This post explains why most of the time you should use enums instead. ENGINEER’S CODEX

Faster Branch Coverage Measurement After nearly two years, Ned thinks this is finally ready: coverage.py can use sys.monitoring to more efficiently measure branch coverage. NED BATCHELDER
