CS1: Unit 3 Review

During a computer science class, Jackson, Ethan, and Scarlett are learning about mouse events in Python. They come across the onMouseMove(x, y) function. What would this function do if they were to use it in their code?

• A) It would be called when the mouse is pressed and moved

• B) It would run code only if a certain condition is true

• C) It would be called every time the mouse is moved, regardless of whether it's pressed or not

• D) It would define a helper function for handling mouse events

Zoe is playing a video game and she wants to move her character. When will the onMouseDrag(x, y) function be called in her game controller?

• A) When Zoe clicks a button on the controller

• B) When Zoe releases a button on the controller

• C) When Zoe presses a button and moves the joystick

• D) When Zoe's controller is stationary

Harper, Mia, and Emma are working on a group project. They want to display a message only when a certain condition is met. Which programming concept should they use?

• A) Defining helper functions

• B) Using an if statement

• C) Handling mouse events

• D) Running code regardless of any condition

Kai is writing a program and he comes across an 'if' statement. He notices some code indented after the 'if' statement. Aria and Maya are discussing what this indented code might do. What do you think is the purpose of this indented code?

• A) It helps Kai define a helper function

• B) It runs regardless of the condition of the 'if' statement

• C) It is called the body and runs only if the condition in the 'if' statement is true

• D) It is used for handling mouse events in Kai's program

Anika has 5 apples and Liam gives her some more. Which test checks if the total number of apples Anika has now is less than or equal to the number of apples William has?

• A) (Anika's apples < William's apples)

• B) (Anika's apples <= William's apples)

• C) (Anika's apples == William's apples)

• D) (Anika's apples >= William's apples)

Avery, Charlotte, and Anika are working on a coding project. They are using an 'if-else' statement. What happens to the code in the 'else' body of their program?

• A) It runs only if the condition in the previous 'if' statement is false

• B) It runs regardless of the condition in the previous 'if' statement

• C) It defines a helper function

• D) It handles mouse events

David is writing a program to automate his home's lighting system. He wants the lights to turn on only if it's dark outside. Which programming concept should he use to achieve this?

• A) Defining helper functions

• B) Testing multiple conditions in a row

• C) Running code only if the mouse is pressed

• D) Handling mouse events

Zoe is working on a large programming project and she has written a function to calculate the total cost of items in a shopping cart. She is considering writing a helper function. What would this helper function do in her program?

• A) Defines mouse events for the shopping cart

• B) Manually calls other functions in the shopping cart program

• C) Runs code regardless of any condition in the shopping cart program

• D) Helps the total cost calculation function perform its work

Liam is writing a program and he has defined a helper function. When can Liam execute this helper function?

• A) Automatically when Liam defines it

• B) Only during mouse events in Liam's computer

• C) Manually when Liam calls it from other functions in his program

• D) Only in the body of an if statement in Liam's code

Emma is writing a program where she needs to use the parameters of a function written by Michael in her own function. Can she do this in programming?

• A) Yes, always

• B) Yes, but only if they have the same name

• C) No, functions cannot use another function's parameters

• D) Only during mouse events
