Worked on establishing the foundational structure for the Boef23/B09_WP4_5_Python repository by creating an initial Python file, xxx.py, which assigns the value 3 to a variable. This minimal implementation provided a concrete, runnable baseline, enabling early validation of development workflows and tooling. The approach focused on Python development, emphasizing reproducibility and ease of onboarding for future contributors. No bug fixes were addressed during this period, as the primary goal was to set up a clear starting point for subsequent feature development and testing. The work laid the groundwork for future integration with continuous integration and testing processes.
