Comment
Domain: Programming Fundamentals
🎯 Motivation
Code tells the computer what to do, but comments tell humans (including yourself) why. They’re ignored by the computer.
📋 Concrete Example
# This calculates the final price after discount - the # makes it a comment. Python skips this line.
🔗 Analogy
Sticky notes on a recipe - ‘this is the spicy version!’ or ‘grandma trick: add a pinch of salt’. The oven doesn’t read them, but you do.
