# 7. Sending a Letter

#1

Please pardon me if any of this is formatted incorrectly, this is my first post .
I am on "Student Becomes the Teacher" lesson 7. Sending a Letter. It is linked above.

When I print my code I receive the following error message "Oops, try again. get_letter_grade(89) returned 'A' instead of 'B' as expected."

My code seems to be returning the incorrect letter grade; however, when I print get_average(lloyd) I see 80.55. I am unsure why my code interpreting 80.55 as an "A". I have looked through similar posts and have been unable to find my error!

"name": "Lloyd",
"homework": [90.0, 97.0, 75.0, 92.0],
"quizzes": [88.0, 40.0, 94.0],
"tests": [75.0, 90.0]
}
alice = {
"name": "Alice",
"homework": [100.0, 92.0, 98.0, 100.0],
"quizzes": [82.0, 83.0, 91.0],
"tests": [89.0, 97.0]
}
tyler = {
"name": "Tyler",
"homework": [0.0, 87.0, 75.0, 22.0],
"quizzes": [0.0, 75.0, 78.0],
"tests": [100.0, 100.0]
}

def average(numbers):
total = sum(numbers)
total = float(total)
result = total/len(numbers)
return result

def get_average(student):
homework = average(student['homework'])
quizzes = average(student['quizzes'])
tests = average(student['tests'])

homework = homework*0.1
quizzes = quizzes*0.3
tests = tests*0.6
return homework+quizzes+tests

if 'score'>= 90:
return 'A'
elif 'score' >= 80:
return 'B'
elif 'score' >= 70:
return 'C'
elif 'score' >= 60:
return 'D'
else:
return 'F'

you made score a string, why? look:

print score # will print lloyd score
print 'score'  # will print string score
