We all have a life to be able to create something. Every day we can put together an event, do meaningful work, or just create memories with each other. Some of the things I have been most proud of creating (as a profession) have been applications and programming. I will share that love and learning in this section.

Learn how to utilize the percent symbol (%) in Python, including classic printf-style string formatting with placeholders like %s, %d, and %f, plus practical examples and best practices for readable, maintainable code.
Use an image concept that visualizes “defining symbols” in programming—such as a clean code editor screen highlighting syntax/identifiers, or an abstract graphic of labeled symbols and characters. Suitable Unsplash searches: “coding”, “programming code”, “developer workspace”, or “syntax highlight”.
