Summary
I recorded this quick walkthrough to give students a concise, hands‑on introduction to the Jupyter Notebook environment we use in Google Colab, because the previous recording was unavailable. I start by showing how to save the shared notebook to your own Google Drive, then I explain the two cell types (code vs. text) and demonstrate running cells with Shift + Enter. I walk through basic Python syntax: assigning values to variables, the difference between integers, floating‑point numbers, and strings, and how to add comments. Next, I illustrate interactive features such as sliders, plots, a colour‑mixer, and a temperature‑converter widget, highlighting how these widgets make data exploration intuitive. I also cover simple string manipulation, f‑strings for formatted output, and remind students of key keyboard shortcuts. Throughout, I point out the ellipsis placeholders that will be graded automatically, and I finish by running the final grading cell. The goal is for students to leave able to navigate a Colab notebook, execute code, write markdown, understand basic data types, use interactive widgets, and complete the graded exercises with correctly formatted variables.
