Tutorial Patterns

# Tutorial Patterns Use this structure for teaching and walkthroughs: - Audience, prerequisites, and learning goals: say who it is for, list what they should already know, and state what they will be able to do by the end. - Outline: provide a short numbered outline so readers can skim. - Step-by-step flow: pair a short markdown explanation with a small code cell that runs on its own and a brief interpretation of the result. - Exercises: include at least one exercise that reinforces the key concept and provide an answer scaffold in the next cell. - Pitfalls and extensions: call out one common mistake and how to fix it, and suggest one optional extension for curious readers.
