Warm Up Activity: Guessing Game

Instructions

Think of a number between 1 and

10. Your partner will try to guess

your number.

Rules

You can only say "higher" or

"lower" after each guess.

Goal

See who can guess the number in

the fewest tries!

What are Comments?

Definition

Comments are notes within your code that are ignored by

the computer. They're meant for humans to understand the

code better.

# This is a comment

print("Hello, world!")

Importance of
Comments

Clarity

Comments help explain what

your code does, making it

easier to understand.

Organization

They can break down complex

code into smaller, more

manageable sections.

Collaboration

Comments make it easier for others to work on your code or

understand your logic.

Comment Syntax in Python

Hash Symbol

Start a comment with a '#' symbol. Everything after the '#' on

the same line is a comment.

Multiline Comments

For multiline comments, use triple quotes ('''comment here''')
