Most Python web frameworks make you choose between testability and convenience. You either have clean code with complex test setup, or you use global state and hope your tests don’t interfere with each other. FastAPI’s Depends() solves this elegantly. Here is an example how you would use it in your API: What’s happening here: Type-safe – […]

In this post, I will build a simple fitness tracker app using Python Reflex. Reflex is a Python library that allows you to create reactive applications using a functional and declarative approach. We will use Reflex to create a simple fitness tracker app that allows you to log the amount of workouts completed per week. […]

The repository pattern is a design pattern that helps you separate business logic from data access code. It does so by providing a unified interface for interacting with different data sources, bringing the following advantages to your system: A practical example Let’s use Python and sqlmodel (PyPI) to demonstrate this pattern (code here): Note: In this implementation, […]

Introduction Two weeks ago I wrote an article about ABCs and interface enforcement. Shortly after I learned that you can do this as well with protocols. Python 3.8 introduced quite a groundbreaking feature that further advanced the language’s capabilities in type checking: the typing.Protocol which allows Python developers to define and enforce interface contracts in […]

Introduction As a Python developer I want to stay up2date with trends and useful tips & tricks. Of course there are great newsletters like Pycoders, but those are already hitting my inbox. Let’s look at Planet Python in this article, an aggregation site/ service that indexes a lot of good Python blog feeds. Keeping an […]

Introduction One cool object-oriented programming (OOP) technique / pattern is enforcing consistent interfaces. In Python you can use Abstract Base Classes (ABCs) for that. 🐍 Using ABCs ensures that all subclasses implement the required methods. This can make it easier to maintain and extend the existing code base. Update Feb 2024: you can also leverage […]

Introduction Python’s versatility in supporting different programming paradigms, including procedural, object-oriented, and functional programming, opens up a rich landscape for software design and development. Among these paradigms, the use of static methods in Python, particularly in an object-oriented context, has been a topic of debate. This article delves into the role and implications of static […]
