As a Python developer who wants to harness the power of object-oriented programming, you’ll love to learn how to customize your classes using special methods, also known as magic methods or dunder methods. A special method is a method whose name starts and ends with a double underscore. These methods have special meanings for Python. Python automatically calls magic methods as a response to certain operations, such as instantiation, sequence indexing, attribute managing, and much more. Magic methods support core […]

When you start your programming adventure, one of the most fundamental concepts that you encounter early on is the array. If you’ve recently switched to Python from another programming language, then you might be surprised that arrays are nowhere to be found as a built-in syntactical construct in Python. Instead of arrays, you typically use lists, which are slightly different and more flexible than classic arrays. That said, Python ships with the lesser-known array module in its standard library, providing […]

After implementing the main functionality of a web project, you may find that your app is rough around the edges. Often, this boils down to the user experience (UX) of your project. For example, when you send a form, you don’t receive a success message, although everything worked fine. You want to build an immersive experience, but wrong URLs display unwelcoming error messages. Luckily, you can get valuable information from Flask through logging. As an admin of a web project, […]

When you’re running a CPU-intensive parallel program, you often want to have a thread or process pool sized by the number of CPU cores on your machine. Fewer threads and you’re not taking advantage of all the cores, more than that and your program will start running slower as multiple threads compete for the same core. Or that’s the theory, anyway. So how do you check how many cores your computer has? And is this actually good advice? It turns […]

Adding a database to your Flask project comes with many advantages. By connecting a database, you’ll be able to store user information, monitor user interactions, and maintain dynamic site content. By the end of this tutorial, you’ll have a robust understanding of how to connect your Flask app to a database and how to leverage this connection to expand your project’s capabilities. Prerequisites You’ll gain the most value from this tutorial if you’ve already created one or more Flask web […]

Flask is a powerful and flexible micro web framework for Python, ideal for both small and large web projects. It provides a straightforward way to get a web application up and running, with all the features that you need to get started. Over the course of this tutorial, you’ll explore the process of creating a boilerplate for a Flask web project. This boilerplate will serve as a great starting point for any scalable Flask web app that you wish to […]
