Top Down Design makes it easier to solve a problem by:

• Starting with the biggest function and then moving to smaller ones

• Making each function hold only one command

• Starting your code from the first command

• Breaking the problem down into smaller parts

Variables allow us to:

• Name different parts of our programs

• Use english words to communicate with Tracy

• Store information to use in our programs

• Change the words Tracy recognizes

How would I collect a number from the user to use for the radius of a circle?

• int(input("What is the radius?: "))

• radius = int("What is the radius?: ")

• radius = int(input("What is the radius?: "))

• radius = int input("What is the radius?: ")

The name color cannot be used for our variable because:

• Variable names cannot only be 1 word

• The word color is already used as a Tracy command

• The word color needs to be capitalized to be used as a variable name

• Variable names must include underscores
