wrrite the python code

JCU Subject results explained shows the percentage score/result you need to get different grades: Below 50% =N 50 up to but not including 65 =P 65 up to but not including 75 = C 75 up to but not including 85 =D 85 and over = HD Note: think about the boundary conditions and don't miss anything. Remember to test your boundaries. Suppose you used 84 as your boundary, e.g, if score > 84 then HD Would that work? No, because what if the score were 84.1? That should be a D, but your code would make it an HD! This is where bugs come from :( Our strong recommendation is that you always use the values in the question In this case, use 50, 85, etc. not 49, 49.9, or whatever. This will help prevent mistakes. Write a function that takes a subject total score and returns the corresponding JCU grade. Check: Are you getting used to this kind of wording? If the function "takes" a score, it means you must pass it into the function as a parameter. If the function "returns" a grade, it means you don't print it, you... return it. Test it! Like we've done before (see the pattern?), write a separate function to test that all the grades can be produced correctly. When your tests all pass, write a main program that asks the user for their score and prints their grade until they enter a score of
