Time is over! You can keep submitting you assignments, but they won't compute for the score of this quiz.
Define a function
add_only_integers that receives two numbers and returns
the sum of them ONLY if they’re both integers. If that’s not the case, the
function should return the string "invalid parameters".
>>> add_only_integers(2, 3) 5 >>> add_only_integers(2, 'what') 'invalid parameters'
