Karel in Python Test (Unit 1)

When it comes to commenting code, what is the primary purpose of comments?

• To make the code look more aesthetically pleasing.

• To hide portions of the code from execution.

• To provide additional information and explanations for developers.

When should you consider updating comments in your code?

• Only during major software releases.

• Never, as comments are static and should not be changed.

• Whenever the code undergoes changes, especially if it affects the logic or functionality.

• Only when requested by team members.

How does top-down design contribute to the development process?

• It introduces unnecessary complexity to the code.

• It facilitates collaboration among team members.

• It limits the scalability of the code.

• It is only applicable to certain programming languages.

What is the role of decomposition in the context of coding?

• To increase the overall code length.

• To combine multiple functions into a single, complex module.

• To break down a problem into smaller, more manageable functions or modules.

• To eliminate the need for functions in the code.

What is the primary purpose of abstraction in coding?

• To complicate the code structure for advanced users.

• To hide unnecessary details and present only essential features.

• To increase the verbosity of the code.

• To slow down the code execution.

How does abstraction enhance code reusability?

• By making the code longer and more complex.

• By encapsulating implementation details and providing a clear interface.

• By avoiding the use of functions.

• By relying solely on detailed comments within the code.

Which command should be used to make Karel turn left in the grid?

• turn_right()

• turn_around()

• turn_left()

• move_left()

What is the purpose of the put_ball() function in Karel programming?

• To delete a ball from the grid.

• To print the current position of Karel.

• To place a ball in the current position of Karel.

• To move Karel to a specific location.

How can you check if there is a ball in the current position of Karel? (based on what we have learned in class so far)

• Use the check_ball() function.

• Use the is_ball() function.

• Use the balls_present() question.

• As of now there is no way to check to see if there is a ball present.

What is the purpose of a for loop in Python?

• To define a function

• To execute a set of commands a specific number of times

• To check a condition and perform actions accordingly

• To create a variable
