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
It's not too bad but I would probably use a dictionary rather
than the list - which avoids the index problem - and I'd do
the int conversion with raw_input::
Grades = {0:'F', 1:'F',2:'F',....8:'B', 9:'A',10:'A'}
score = int(raw_input("What's your exam score (0-100)? "))
print "Your grade is:", Grades[score/10]
