Biomedical Engineering Student Refactors Hangman Game to Learn Python Code Structure

A biomedical engineering technology student has documented their Python learning journey by refactoring a self-built Hangman game from a single-block script into a modular, function-based version. The original v1.0 worked correctly but became difficult to manage as all game logic — input handling, validation, win/loss checks — was bundled into one continuous loop. In v2.0, the student separated responsibilities into distinct functions, making each component easier to locate, understand, and modify independently. Input validation was also added to reject multi-character or non-alphabetic entries, and a Python set was introduced to track previously guessed letters. The project serves as a practical example of how beginner programmers can progress from making code work to structuring it well.
