How to make refactoring part of your Definition of Done Writing code is an iterative process. The first iteration is usually not the best result. Grooming and polishing ✨ are needed before the code is ready to share with the world (and your future self). There is a saying in software development that illustrates the […]
Python allows you to use *args and **kwargs in function definitions to accept an arbitrary number of positional and keyword arguments, respectively. Here is a simple example: Different types of function arguments In the above example, the arbitrary_args function is defined to accept any number of positional and keyword arguments using the *args and **kwargs […]

In this article I will give you 10 tips for cleaner code. Hope this helps improve your Python code. 1. Smaller units. Break long functions (methods) into multiple smaller ones that do one thing (SRP or “Single-responsibility principle”). This will make your code more modular and easier to test. For example, a function that parses […]

A single class, several thousands lines of code, no tests available 😮 You might scratch your head and say WTF?! After all, good developers decouple code into manageable pieces […]
