Developed and delivered a Python introductory notebook for beginners in the Odin2325/TQ5Juli repository, focusing on user input, string formatting, area and distance calculations, and compound interest exercises. The work involved creating clear, hands-on exercises in Jupyter Notebook to support onboarding and self-paced learning for new Python developers. Additionally, an existing notebook was refactored to improve prompts and streamline basic arithmetic operations, enhancing clarity and usability. The technical approach emphasized reusable assets and traceable commits, with all features implemented using Python programming within the Jupyter environment. No major bugs were addressed, as the primary focus remained on feature delivery and onboarding enablement.
