1) What do I need to do?
🎯 Your mission: Bug hunt: the secret door
This code has 3 bugs. Fix them so it prints Access granted.
2) What do I need to know?
if: do it only when it's True
if checks a question. If it's True, Python runs the lines underneath.
The if line ends with a colon : and the lines inside are pushed in with 4 spaces. This is called indenting.
🧰 Your toolkit for this mission
Everything you need to know to finish this lesson on your own:
if
Run some code only when a question is True.
How to write it: Write if question: — don't forget the colon — then indent (4 spaces) the lines underneath.
if score >= 90:
print("Legend")elif
"Else if" — another question to try if the ones before were False.
How to write it: Same line up as if, with its own question and colon.
elif score >= 50:
print("Hero")else
"Otherwise" — runs when none of the questions were True.
How to write it: else: has no question, just a colon.
else:
print("Sidekick")Order matters
Python checks top to bottom and stops at the first True one.
How to write it: Put the hardest test first (90 before 50).
Comparing text
Check what the player typed.
How to write it: Use == and quotes: if weather == "sunny":. Spelling and capitals must match exactly.
weather = input("Weather? ")
if weather == "sunny":
print("Solar power!")Think about it
