Create /basic/input resource

[neumannrf]

As a user
I need to input a list of integers
So that it can be manipulated.

Assumptions:

• There should be a main.py file with the following content below the /answer block.

@basic_ns.route('/input/<string:csv>')
@basic_ns.doc(params={'csv': 'Comma-separated integer values.'}, description='Inputs list.')
class InputList(Resource):
    def post(self, csv):
        my_list.clear()
        my_list.extend(bs.csv_to_list(csv))
        return my_list

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

from src import basic_services as bs

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

def csv_to_list(csv_string):
    """
    Converts a string with comma-separated integer values to a Python list of integers.

    Receives
    --------
    csv_string : string
        Comma-separated integer values (stored as strings).

    Returns
    -------
    integer_list : list
        List of integer values.
    """

    string_list = csv_string.split(',')
    integer_list = list(map(int, string_list))
    return integer_list

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

from src import basic_services as bs


def test_csv_to_list():
    assert bs.csv_to_list('1') == [1]
    assert bs.csv_to_list('1,2') == [1, 2]
    assert bs.csv_to_list('1,2,3') == [1, 2, 3]

Acceptance criteria:

Given that integer lists should first be input before manipulated
When this resource is called
Then an integer list is input into the application.
