Thank you! Part 1 what is wrong with this loop? while i "h, e, I, I, o" # "one two." -> "o, n, e, , t, w, o, !" #"a" def eachChar(str): Part 4 Write a new function called sumofThrees (n), which returns the sum of first n positive integers that are divisible by 3. If n is less than or equal to 0, return 0. /In 3 will return the integer 18 because 3 6+ 9 // n5 will return the integer 45 because 3 6 + 9 1215 -45 = 18 // n = -1 will return def sumOfThrees (n)
