Hello!!
I just completed exercise 7 (chapter 4) in Zelle's book:
"A certain CS professor gives 100-point exams that are graded on the
scale 90–100:A, 80–89:B, 70–79:C, 60–69:D, 60:F. Write a program that
accepts an exam score as input and prints out the corresponding grade."
I am quite happy with my code, but there is a bug: if the score is 100,
then the program calculates 100/10 = 10. However, the tuple runs to 9,
leaving me with an error message: IndexError: tuple index out of range
I can't figure out how to solve that problem...
I also suspect that my code clearly exposes me as a beginner :-) What
would be the pythonic way of solving that exercise?
# exam score to grade conversion
# Zelle, ch. 4, exercise 7
x = ("F", "F", "F", "F", "F", "E", "D", "C", "B", "A")
score = raw_input("What's your exam score (0-100)? ")
grade = x[int(score)/10]
print "Your grade is:", grade
I greatly appreciate your comments!
David
