“Don’t Repeat Yourself” (DRY) is one of the first principles that every programmer encounters in the early stages of their coding journey. Some of us even had to learn it the hard way. We promised ourselves to avoid repetitive code to never again deal with the extensive refactoring required for every small change.

This simple principle has found a fundamental place in every programmer's heart. It may also be the reason why, from time to time, every programmer doubts their code and begins to refactor it in the early stages of coding.

This talk provides an overview of different solutions for preventing code repetition. We will start with the most common solutions, such as using functions and classes, and then explore more intermediate approaches for managing similarly structured repositories with the help of open-source template libraries such as Copier and Cookiecutter. Finally, we will address a more complex problem and examine how to automate updates using open-source tools like Renovate Bot.

As a takeaway, participants will gain insights into various solutions and a glimpse into the usability of each open-source library. Participants are also encouraged to reconsider the entire process: Are these solutions truly preventing repetitive code, or are we merely caught in an endless cycle of automation?
