How would I ask the user to input 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?: “)

What is the correct way to ask a user for a color and store the answer as a variable?

• color = input(“Enter a color: “)
• user_color = “Enter a color: ”
• input(“Enter a color: “)
• user_color = input(“Enter a color: “)

The name ‘color’ cannot be used as a variable name 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

Why are parameters useful?

• They allow us to tailor functions to be used in multiple situations
• They allow us to change the order of commands in a function
• They give us the ability to use variables in loops
• They allow the user to give input

How many parameters can we use in each function?

• 1
• 2
• 4
• As many as we need
