CMU CS Academy Unit 5

Read through the following lines of code that contains an error. What should be done to fix the error?

Line 1: a = 1

Line 2:

Line 3: if a = 1:

Line 4: print(“A”)

Line 5: print(“B”)

• Line 2 needs to be fixed. Conditional statements use == for equivalent conditions.

• Line 5 needs to be fixed. This needs to have an else before it so that it can execute if the condition is not true.

• Line 3 is missing parentheses around the condition. Conditional statements always include parentheses.

• Line 2 is missing a declaration of the variable b. The conditional statement will have an error with only one variable.

Which of the following is a valid call to the function g and will have f(x) called 3 times?

def g(x,y):

if (x < 5):

f(x)

if (y < 10):

f(x)

f(x)

• g(5, 10)

• g(10, 5)

• g(4, 5)

• g(4, 10)

Which of the following calls to onMousePress will do nothing?

def onMousePress(mouseX, mouseY):

if (mouseX != mouseY):

Circle(mouseX, mouseY, 10, fill=’mediumVioletRed’)

• onMousePress(100,200)

• onMousePress(100,400)

• onMousePress(200,100)

• onMousePress(300,300)

Which of the following is false about naming functions and parameters?

• Names can have spaces.

• Names can have digits.

• Some names are reserved by python.

• Names cannot start with digits.

Which of the following would be a legal call for the code below?

def drawPrettyStar(numberOfPoints, radius, color):

Star(200, 200, radius, numberOfPoints, fill=color)

• drawPrettyStar(5, 30, ‘red’)

• drawPrettyStar(5, ‘blue’, 40)

• drawPrettyStar(‘purple’, 20, 35)

• drawPrettyStar(‘4’, ‘5’, blue)
