The dragon explains

The Dragon's Full Sheet

  1. The dragon: You know three things now: make a box, change a box, and print several boxes together.

  2. The dragon: Making one: put a value in, no print yet.

    example.pyPython 3
    gold = 100

  3. The dragon: Changing one: read the old value, work out the new one, save it back.

    example.pyPython 3
    gold = gold + 30

  4. The dragon: Printing several, labelled: words and boxes mixed with commas — and it shows the UPDATED value.

    example.pyPython 3
    print("Gold:", gold)
    OutputGold: 130

  5. The dragon: The challenge ahead just asks you to use all three, in the right order.

Quick check

Check your understanding

Say your answer out loud before reading the marked one. Every wrong option is a mistake real beginners make.

  1. Question 1 of 1

    gold = 100, then gold = gold + 30. What does print(gold) say?

    question.pyPython 3
    gold = 100gold = gold + 30print(gold)
    • 130Correct
    • 100
    • 30

    Why: 100 + 30 = 130, and that gets saved back into gold. The box remembers the update.
