CurriculumThe Dragon Decides

Python if, elif and else for Kids

An if statement lets a program do something only in certain situations, instead of doing the same thing every time.

What this topic covers

Before a child can write an if statement, they need to believe that a comparison like gold > 100 is itself a value — something Python works out to True or False, the same way it works out 40 + 2. The topic starts there, with comparisons on their own, before any if appears.

Then comes if by itself: doing something when a question is True, and nothing at all when it is not. That 'and nothing at all' is deliberately given its own space, because a branch that does nothing visible is genuinely harder to reason about than one that does something.

elif and else follow, and with them the idea that the order of checks matters — a chain that tests the loosest condition first will never reach the more specific ones below it. That is the single most common source of 'my code runs but gives the wrong answer' at this level, so the closing challenge is built specifically to expose it.

Python from this topic

gold = 42
if gold > 100:
    print("Rich")
else:
    print("Not yet")

Output

Not yet

The mistake this topic is built to fix

Common mistakeA child believes every branch of an if/elif/else runs, one after the other, like ordinary lines of code.

This is a documented and stubborn misconception: the child reads the code top to bottom and assumes each line executes in turn. The topic uses cases where a wrong order produces a plausible-looking but wrong answer, so the mistake is visible rather than silent.
