A programmer wants a method to calculate a discounted price so that other code can store the result, compare it, or use it in another calculation. Which design best meets this requirement?

A
The method must print the result instead of returning it.
B
The method must return the result so the caller can use it.
C
The method must store the result in a global variable.
D
The method must define an additional parameter for the result.

A method contains tax = price * tax_rate and total = price + tax. What is normally true about tax and total?

A
They can be accessed directly from every method in the program.
B
They automatically become parameters of the method that called them.
C
They are normally accessible only within the method that created them.
D
They remain available globally after the method finishes.

A recursive method repeatedly calls itself while solving a problem. What must it include to terminate the repeated calls?

A
A global variable that stores every previous result.
B
A base case that stops the repeated calls.
C
A print statement that displays each recursive call.
D
A default parameter that changes the method name.

Select all benefits that the material associates with decomposing a grade-processing program into focused methods.

A
Each method can have a narrower responsibility.
B
Methods can be tested independently.
C
Every method must handle input, calculation, display, and file storage together.
D
Errors can be isolated to a smaller section of code.
E
A change to one responsibility can often be made in its focused method.

What programming concept hides implementation details behind a meaningful operation such as calculate_total()?

Open ended

1 point

You are designing a program that processes an order. It must validate the items, calculate a total, and create a receipt. Explain how you would decompose this program into reusable methods, including how the methods should communicate and why this design is preferable to one large procedure.

Given def create_label(text, prefix="Item"): followed by create_label("Notebook") and create_label("Notebook", "Product"), which result is produced by each call?

A
Both calls return Notebook because the prefix is always fixed.
B
The first call returns Item: Notebook, and the second returns Product: Notebook.
C
The first call returns Product: Notebook, and the second returns Item: Notebook.
D
Both calls cause an error because default parameters cannot be used with strings.

Which statement correctly describes a variable created inside a method?

A
A variable created inside a method can normally be accessed directly from any other method.
B
A variable created inside a method is normally local to that method.
C
A parameter belongs to the caller rather than to the method being called.
D
A return value can be accessed only while the method is still running.

A program must validate grades, calculate an average, assign a letter grade, and display a report. Which design best applies decomposition?

A
Put every operation in one large method so that the program has fewer method calls.
B
Create a separate method for every individual line, regardless of what that line does.
C
Divide the problem into focused methods such as validating input, calculating a result, and creating a report.
D
Store all intermediate values in global variables so that every method can use them.

True or false

Consider these methods:

def printed_square(number):
print(number * number)

def returned_square(number):
return number * number

What is the important difference between calling printed_square(5) and assigning result = returned_square(5)?

A
Both methods make 25 available in result because printing and returning are interchangeable.
B
Only returned_square(5) can provide 25 as a result that the caller can store.
C
Only printed_square(5) can provide 25 to the caller because printed output is automatically returned.
D
Neither method produces 25 because a method must accept at least two parameters.

Given def add(first, second): return first + second, what does add(7, 4) return?

A
The call returns 3 because the second argument is subtracted from the first.
B
The call returns 28 because the arguments are multiplied.
C
The call returns 74 because the arguments are joined as text.
D
The call returns 11 because 7 is assigned to first and 4 to second.
