Dynamic vector initialization

Create a function that initializes a dynamic one-dimensional list with a specified size. The function should return the initialized list. Use 0.0 as the initial value of each element.

Use a nonnegative integer size. The returned vector is a one-dimensional Python list. A size of 0 returns an empty list; each call creates a new list.

Complete the supplied function in Listing 1. Keep its signature and use the checks below it.

Listing 1: Starter function and supplied checks for dynamic vector initialization.

def initialize_dynamic_vector(size: int) -> list[float]:
    # Add code here!
    pass


def test_initialize_dynamic_vector() -> None:
    size = 5
    my_dynamic_list = initialize_dynamic_vector(size)

    assert len(my_dynamic_list) == size
    assert my_dynamic_list == [0.0, 0.0, 0.0, 0.0, 0.0]

    print("Dynamic List Elements:")
    print(my_dynamic_list)


test_initialize_dynamic_vector()

TipHint

len(values) returns the number of elements, so len([3, 7]) is 2 and len([]) is 0. List indexing starts at 0: [3, 7][0] is 3. An index must refer to an existing element.

assert condition stops the check with an AssertionError when the condition is false.
