No, please don't! input has several security issues, it is

Not sure how the dict is better - in either case, leaving off the

The value returned from raw_input() is a string; you have to convert

I think tuple unpacking makes code like this more readable:
for lower, upper, grade in grades:
if lower <= score <= upper:

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

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
