Question 7 Create a function sumsquares () which, for a whole number n > 0, returns the sum of squares of all the whole numbers up to and including n. If n is not a whole number (i.e. not a non-negative integer), use the statement raise ValueError("Sorry, n must be a whole number!") in your code to report the error. Do NOT change the error message. Here are some examples: sumsquares (0) 0 sumsquares (2) 5 sumsquares (2.3) ValueError: Sorry, n must be a whole number
