    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. This is how it will look: Install Reflex After making a new directory and cd’ing into it, I’ll use uv (anybody not yet using this amazing tool? 💡) to initialize a project and install Reflex: The awesome thing about uv is that you don’t have…

    What is this pattern about? The Pipeline design pattern (also known as Chain of Command pattern) is a flexible way to handle a sequence of actions, where each handler in the chain processes the input data and passes it to the next handler. This pattern is commonly used in scenarios involving data processing, web scraping, or middleware systems. In this blog post, I’ll walk you through a specific example that leverages Python’s powerful functools.reduce and partial functions, along with the BeautifulSoup library for parsing HTML content. This code showcases the Pipeline pattern applied to HTML table extraction and processing. What…

    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, we did not add error handling to keep the example relatively small. You should ensure that if something goes wrong (e.g., database connection issues or file access errors), the program can handle the error gracefully and provide useful feedback. The example might be a bit…

    We are excited to announce that we’ve extended our Newbie Bites from 25 to 50 Python exercises! 🎉 The importance of exercising when learning how to code 💡 We’re passionate about this new batch of exercises because they require active engagement, which is crucial for learning how to code. Passive methods like reading books or watching videos don’t help concepts click or stick. Our exercises involve writing code that is validated with pytest. This immediate feedback helps you understand mistakes and learn more effectively. You’ll encounter errors, re-think your approach, and practice deliberately. Why double the number of Newbie exercises?…

    OpenStreetMap (OSM) is known for being an open source project that allows people to browse the world map and to plan routes. However it is more than that. Among others it provides a read-only API that allows users to query for very diverse map data: Overpass API Data structure of OSM To understand the structure of the queries, we first need to understand how OSM saves its data. OSM uses basic data structures: node, way, and relation. Each element can have multiple tags, which consist of a key-value pair and they help specify the features of each element. Nodes also…
