Python Programming Quiz

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)

Using the same code segment from #2, which of the following is not a parameter of the function

drawPrettyStar?

def drawPrettyStar(numberOfPoints, radius, color):

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

• numberOfPoints

• radius

• color

• fill

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

• g(5, 10)

• g(10, 5)

• g(4, 5)

• g(4, 10)

Which of the following results in a red rectangle being drawn when the mouse is moved in the left half of the canvas and a green rectangle being drawn when the mouse is moved elsewhere? (Assume the function drawRect will draw a rectangle given the color)

• if(mouseY <= 200)

• if(mouseY <= 100)

• if(mouseX <= 100)

• if(mouseX <= 200)

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

• The Rect function is not called correctly and needs an extra parameter.

• The draw function is defined incorrectly since you cannot define a function without parameters.

• The draw function is called too early. Line 1 should be on Line 5.

• There are no errors with the code as it is.

Which of the following can be using to shorten the code on Lines A and B to be contained with one line of code?

• else if b == True

• else b == True

• elif b == True

• if b == True

Which of the following is a true statement about how many parameters a function can use in its declaration?

• None – functions can never contain parameters

• One – functions can only contain one parameter

• Multiple – functions can contain multiple parameters as long as they are real words in the English language

• Multiple – functions can contain as many parameters as needed

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

• Line 3 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.
