Update evaluate.py

kyu_2/evaluate_mathematical_expression/evaluate.py:173 in public function `check_conditions`:
        D401: First line should be in imperative mood (perhaps 'Normalize', not 'Normalizing')

        [Docstring] prescribes the function or method's effect as a command:
        ("Do this", "Return that"), not as a description; e.g. don't write
        "Returns the pathname ...".
