Create /math/cube resource

[neumannrf]

As a user
I need to cube each element in the list
So that so that calculations can be automated.

Assumptions:

• There should be a main.py file with the following content.

@math_ns.route('/cube')
@math_ns.doc(description='Takes the cube of the list.')
class CubeList(Resource):
    def put(self):
        return ms.cube_list(my_list)

• The main.py file should include an external file above the from src import basic_services as bs line.

from src import math_services as ms

• There should be a src/math_services.py file with the following content

def cube_list(integer_list):
    """
    Takes the cube of every integer in the list.

    Receives
    --------
    integer_list : list
        List of integer values.

    Returns
    -------
    cubed_list : list
        List of the cubes of integer values.
    """

    cubed_list = [x**3 for x in integer_list]
    integer_list.clear()
    integer_list.extend(cubed_list)
    return integer_list

• There should be a test/math_test.py file with the following content.

from src import math_services as ms


def test_cube_list():
    assert ms.cube_list([]) == []
    assert ms.cube_list([1]) == [1]
    assert ms.cube_list([2]) == [8]
    assert ms.cube_list([1, 2]) == [1, 8]
    assert ms.cube_list([1, 2, 3]) == [1, 8, 27]

Acceptance criteria:

Given that the application stores a list of integers
When this resource is called
Then each integer number in the list is cubed.
