Bob Gailer's solution is so elegant. Can someone plese explain what is the algorithm behind string.maketrans. More exactly, how is this function doing the coding?
Actually, I don't think the point was to be elegant as much as to get you thinking about something you might not have explored--never hurts to keep learning new features so you don't inefficiently apply the same old small set of things to new problems. You wouldn't *really* want to implement a production grade system like that, cute though it is. This is setting up a translation table mapping the first character in the score to a letter grade. So a 9 is changed to an A. The obvious problem though is how it handles a score of, say, "1". Or, for that matter, "37".
