I. forward(100) II. backward(-100) III. forward(-100) - I and II How far does Tracy need to move from the starting position to reach the right side of the canvas? - 200 pixels If you want Tracy to move forward 100 pixels without making a line, what set of commands should you write? - penup() forward(100) Tracy always starts facing which direction? - East If Tracy is facing right, which of the following commands can be used to turn her to face up? I. left(90) II. turn(up) III. right(-90) IV. setposition(90) - I and III If Tracy started facing right, which direction would she be facing after we ran the following code? 1. left(90) 2. left(90) 3. right(90) - Up Which of the following is NOT a reason for loops are useful when writing code? - Loops let us make shapes of multiple sizes The following loop draws 3 circles on the screen. If I wanted to alter this loop to draw 10 circles, how many lines would my code be? 1. for I in range(3): 2. circle(25) 3. forward(50) - 3 lines If Tracy starts at the left edge of the canvas and moves forward 50 pixels, how many times will this code need to be repeated to have Tracy reach the right edge of the canvas? - 8 times Which lines of the code below will be repeated 4 times? 1. penup() 2. for I in range(6): 3. pendown() 4. circle(25) 5. forward(50) ard(200) - 3, 4, and 5 Why do certain words change color in Python? - To show that they are recognized as key words If I use the command right(180), which way will Tracy turn? - She will turn around The setposition() command moves Tracy to a coordinate and: - Does not turn her If you wanted Tracy to complete her command immediately, which speed value would you use? - 0 If you want three circles to be drawn next to each other (as seen in the image below), after drawing the first circle, how far would you need to move Tracy before drawing the next circle? - The circle's diameter Comments are: - Written for humans to read and understand What symbol is used at the beginning of an in-line comment? - # What punctuation is needed to begin a multi-line comment? - """ Which of the names below follow all naming rules? 1. my_function 2. Draw a Circle 3. 4_circles 4. make_square - make_square If I am creating a function that is going to draw 2 squares, which of the following would be the best name option? - draw_squares Which of the following is NOT a way functions make our code more readable? - Each function only contains one command What two things must be included in your function definition? - A function name and commands to be performed
