Quotes hold text
Words for people live between quotes: "hello".
01PYTHON'S MARKS
Tiny marks have jobs.
A quote, colon, or bracket is not decoration. It gives Python a clue.
USE THESE SOON
Six marks to notice first.
Parentheses hold what a command needs
print("hello") keeps the message inside them.
One equals stores a value
color = "orange" gives a value a name.
A colon opens a block
After if or for, it says: “the steps start here.”
A hash starts a note
Python ignores the note. It helps a person remember.
An underscore joins words
robot_color is one clear name without a space.
Meet four more. You do not need to use them yet.
Brackets hold a list
A list keeps several items in order: ["moon", "star"].
Braces hold a collection
Later, Python can use them for labeled pairs or unique items.
A slash can divide
10 / 2 asks Python to divide ten into two parts.
A backslash changes the next mark
Inside text, \n means: start a new line.
Recognizing a mark is enough today. Its full lesson can wait.
YOUR TURN
Give each mark its job.
Try each tiny question. A wrong answer becomes something to review.

BIG IDEA
Every mark has one small job.
You do not need all of them at once. Look only for the mark used in today's idea.
