What are comments?

Comments are notes that people write when they’re working on something, so others (or themselves later) can understand what’s going on.

Imagine you're playing with building blocks. You stack them up to make a tower, but then you write a little note beside it saying “This is the strong part” or “Don’t touch this one!” Those notes are like comments, they help explain what you did, without changing the tower itself.

How Comments Work

When someone writes a program (like a game or a calculator), they use comments to write little messages for themselves or others. These messages don’t affect how the program works, they’re just there to help people understand it better.

For example, if you see this line in a program:

print("Hello, world!")

You could add a comment next to it like this:

# This line says "Hello, world!" to start the game

The # is like a special marker that tells the computer, “this is just a note, ignore it!” So the program still works the same way.

Comments are like little helpers who whisper in your ear while you're building something cool.
