Tutorial 3 of 8

Read a lesson with the AI tutor beside you

A lesson is a short read with the code built in. Expect about fifteen minutes, not a textbook chapter. The AI tutor sits in the right-hand column the whole way down, before you need it.

  1. Step 1

    Open a lesson and get your bearings

    1. Open a lesson, for example Variables and print() at /student/lesson/lesson-01-variables-and-print.
    2. The breadcrumb at the top shows Dashboard, then Course, then this lesson.
    3. The gold button at the top right reads Practice exercises · earn 350 XP. That is where the graded work lives. Read first, then click it.
    4. Skim the learning objectives. They tell you what you should be able to do by the end.
    A lesson page. The left column has the lesson title, learning objectives, and reading text. The right column holds a pinned AI tutor card headed 'AI tutor — Guided learning, I ask before I answer', with a chat box at the bottom.
    A lesson page. The tutor rail on the right follows you down the page.
  2. Step 2

    Read, then check yourself

    1. Read the explanation and the Examples block. The examples are short on purpose.
    2. Answer the Checkpoint questions as you reach them. You get feedback right there, and a wrong answer costs you nothing.
    3. Do not skip the checkpoints. They are the cheapest way to find out you misread something.
  3. Step 3

    Run code inside the reading

    1. Scroll to Hands-on coding. The dark block is a real editor, not a picture of one.
    2. Click Run. Your output appears under the editor in the OUTPUT panel.
    3. Change something and run it again. Breaking the example on purpose is a good way to learn what the error messages mean.
    4. If the editor header says loading… and Run is greyed out, Python is still downloading. It is about 12 MB, once, and your browser keeps it after that.

    Tip. Fill-in template is a switch at the top right of the editor. Turn it on and every line collapses to a skeleton like _____("_______"), which helps when you do not know how to start. Turning it off gives your typed code back.

  4. Step 4

    Use the extras at the bottom

    1. CodeLens steps through a program one line at a time and draws the variables and the objects they point at. Click Trace to start, then use ◀ Prev and Next ▶.
    2. Debugging interlude asks you to predict the error before you fix it. Predicting first is the point.
    3. At the very bottom, every lesson names its source, its chapter, what was rewritten, and its license.

    Tip. Walk through CodeLens once per new concept. One full step-through is usually all it takes for a thing to click.
