Your task is to write function findSum. Upto and including n, this function will return the sum of all multiples of 3 and 5. For example: findSum(5) should return 8 (3 + 5) findSum(10) should return 33 (3 + 5 + 6 + 9 + 10) Solution: def find(n): return sum([i for i in range(1, n+1) if i%3 == 0 or i%5 == 0]) 1. Find a number less than 'n'. 2. Find a number that is divisible by 3 or divisible by 5..
