Part of the whole-letter grade


#1

I am getting the answer as B even I am not calling get_letter_grade function. I thought the result would be in numbers. ANyone please explain the working

what changes should i make so i see the number grade too?

lloyd = {
"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]
}

Add your function below

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"])
total_weight=0.1*homework + 0.3*quizzes + 0.6*tests
return total_weight

def get_letter_grade(score):
if score>=90:
return 'A'
elif score>=80:
return 'B'
elif score>=70:
return 'C'
elif score>=60:
return 'D'
else :
return 'F'
print get_letter_grade(get_average(lloyd))

print get_letter_grade(get_average(lloyd))

def get_class_average(students):
results=[]
for student in students:
results.append(get_average(student))
return average(results)

You should just get a letter grade for this lesson. And B is the correct letter grade. Do you have a specific error or where you just worried your correct code should have included a number grade as well?
