How you'll be checked
Each lesson pairs a short explanation with 2–3 exercises, graded deterministically on your device:
🔮 Predict the output
Read a snippet and say exactly what it prints — the fastest way to build a mental model of how Python runs.
✏️ Fill the blank
Complete the missing token so the code does what the prompt asks. No syntax hand-holding.
🔢 Order the lines
Drag shuffled lines back into the sequence that produces the right result.
✅ Pick the answer
Choose the correct statement about behaviour, output or a concept.
