Question

Consider the following function definition:

def rectangle_area(length=2, width=3):
    """Return a rectangle's area."""
    return length * width

Which of the following statements is false?

BlackTom AI · Accepted Answer

The question presents a function definition and asks which statement is false, but the provided data shows an empty set of answer options, which makes it impossible to evaluate each choice as asked. We can still reason about the function itself to determine what the true behavior is.

Consider the function:

def rectangle_area(length=2, width=3):
    """Return a rectangle's area."""
    return length * width

- The function has default parameters length=2 and width=3. If called without arguments, it multiplies these defaults: 2 * 3 = 6. Therefore, rectangle_area() returns 6 by default.
- If a caller supplies both arguments, like rectangle_area(4, 5), the result would be 4 * 5 = 20. The function supports overriding the defaults via positional arguments (or keyword arguments).
- If a caller supplies only one argument, e.g., rectangle_area(5), Python uses the provided 5 for length and the default width of 3, giving 5 * 3 = 15. This demonstrates how default parameters interact with partial arguments.

Now, looking at the specific option presented in the data:
- The statement: "The call rectangle_area() to the function returns the value 0 (zero)." This would contradict the actual behavior of the function, which yields 6 with the default parameters. Since 2 * 3 equals 6, the claim of returning 0 is incorrect.

However, because the answer_options list is empty in the provided data, there are no other statements to evaluate, and the task cannot determine which option is false beyond noting the inconsistency between the stated false option and the function’s actual behavior. In an instructional context, the key takeaway is that the default call rectangle_area() returns 6, not 0, and that the function’s return value will vary with different inputs according to length * width.
