Don't understand this section, trying to rate a book. Not working for me. I also do not understand why the codes change colors, how can I find out what each color mean? There is red, yellow, purple, light blue, and white.

types.swift
// Enter your code below
let title = "A Dance with Dragons"

var = "rating"

"\(title) \(rating) is \(7.5)"

Here is the instructions for this:

Every book in our store has a rating so that customers can sort through selections. In this task, declare a variable named rating and assign the value 7.5

Hey Matt Conway,

The multiple colors on the code help you differentiate between the different parts of the code. The green is used on the comments, the pink indicates a string, the orange indicates a keyword var or let, and the white is the variable or constant name. These colors can be different from what you see in your playgrounds.

As for the question, this is an easy one. You're just over thinking it. You need to create a variable called rating and assign it the value of 7.5.

var rating = 7.5

Good Luck!
