Building an Interactive Python Code Viewer and a Wheel of Life Visualization As developers, we often share Python scripts with colleagues, students, or clients. However, raw .py files are not always the easiest format to read or explore, especially for people who are not familiar with development tools. To address this, I created a self-contained Python-to-HTML code viewer that converts any Python script into an interactive web page. This viewer makes Python code easier to read, search, and navigate, directly from a browser. Wheel of Life – Balance Across Key Areas As an example, I used the tool to present a Python script that generates a visual “Wheel of Life” diagram, a framework often used in coaching and personal development. The Wheel of Life illustrates eight key areas that influence overall balance: Physical Environment Career / Work Financial Security Health / Wellbeing Family / Friends Relationship / Romance Personal Growth…
