How Python Code Runs: The Full Picture, for Kids

Order, no gaps, no auto-repeats, changes only forward — everything at once.

The Assistant's Final Check

You've learned three things about how the assistant reads your code. Let's put them together.

One: top to bottom, always, exactly as written.

print("A")
print("B")

Output

A
B

Two: nothing happens unless you actually wrote it — no gap-filling, no guessing, no auto-repeating.

Three: a change is only visible to the lines that come AFTER it. Earlier lines can't see the future.

That's everything. The challenge ahead just asks you to use all three at once.

A gate is FIND KEY, then USE KEY, then UNLOCKED. What does the line right after FIND KEY say about the gate?

print("LOCKED")
print("FIND THE KEY")
print(???)

Why: Still LOCKED. Only the line that changes the gate's state changes it — finding the key, on its own, changes nothing.
