Functions organize code into reusable units and can accept inputs and produce outputs.

2. QuestionMultiple choice

What is a parameter?

Please select an answer first.

Correct answer: B

The correct answer is A named input listed in a function definition.

  1. Identify the programming concept: Determine whether the question asks about an algorithm, data, control flow, a function, debugging, efficiency, security, or ethics.
  2. Trace the logic: A parameter is a placeholder that receives a value when the function is called.
  3. Check the conclusion: The correct answer is A named input listed in a function definition.

A parameter is a placeholder that receives a value when the function is called.

3. QuestionMultiple choice

What is an argument?

Please select an answer first.

Correct answer: C

The correct answer is The actual value passed to a function when it is called.

  1. Identify the programming concept: Determine whether the question asks about an algorithm, data, control flow, a function, debugging, efficiency, security, or ethics.
  2. Trace the logic: An argument supplies the value that corresponds to a function parameter.
  3. Check the conclusion: The correct answer is The actual value passed to a function when it is called.

An argument supplies the value that corresponds to a function parameter.

4. QuestionMultiple choice

What does a return statement do?

Please select an answer first.

Correct answer: D

The correct answer is It sends a result from a function back to the calling code..

  1. Identify the programming concept: Determine whether the question asks about an algorithm, data, control flow, a function, debugging, efficiency, security, or ethics.
  2. Trace the logic: Return makes a function's computed value available to the code that called it.
  3. Check the conclusion: The correct answer is It sends a result from a function back to the calling code..

Return makes a function's computed value available to the code that called it.

5. QuestionMultiple choice

What is a list or array?

Please select an answer first.

Correct answer: A

The correct answer is An ordered collection of values.

  1. Identify the programming concept: Determine whether the question asks about an algorithm, data, control flow, a function, debugging, efficiency, security, or ethics.
  2. Trace the logic: Lists store multiple elements in an order so a program can access, update, and process them.
  3. Check the conclusion: The correct answer is An ordered collection of values.

Lists store multiple elements in an order so a program can access, update, and process them.

6. QuestionMultiple choice

What is an index?

Please select an answer first.

Correct answer: B

The correct answer is A position used to access an item in a sequence.

  1. Identify the programming concept: Determine whether the question asks about an algorithm, data, control flow, a function, debugging, efficiency, security, or ethics.
  2. Trace the logic: An index identifies an element's location in a list or string; many languages begin counting at zero.
  3. Check the conclusion: The correct answer is A position used to access an item in a sequence.

An index identifies an element's location in a list or string; many languages begin counting at zero.

7. QuestionMultiple choice
