Method: findGrade (points: float): Points - 10 This method should determine the grade of the passed point value. Grades should be rounded appropriately (ie 89.5 is an A, 79.5 is a B and so on). This should print the letter grade based upon the passed parameter Method: findGrades(): Points - 10 This method should print the letter grades of an undetermined number of scores. This method should call method findGrade(points: float) appropriately and should continue to ask for grades until a flag is entered to stop the loop. The user should be aware of the flag Method findDigitSum(value: int) : Points - 15 This method should sum all the individual digits of the value passed by parameter. It should then display the sum (ie if 243 is passed to the parameter it should display 9 as the sum, b/c 2 + 4 + 3 = 9) Method:isPalindrome(word: str): Points - 15 This method should display if the word passed by parameter is a palindrome. A palindrome is a word or phrase that is spelled the same forwards and backwards (ie racecar is a palindrome... spelled the same from left to right and right to left)
