The code prints OK, but checker claims error. Whats worng


#1

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 = float (sum (numbers))
total = total/len(numbers)
return total

def get_average (student):
homework = average (student['homework'])
quizzes = average (student['quizzes'])
tests = average (student['tests'])
return 0.1*homework + 0.3*quizzes + 0.6*tests

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")

get_letter_grade (get_average(lloyd))

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

average = get_class_average ([lloyd, alice, tyler])
print (average)
print (get_letter_grade (average))

I think you are missing defining students as [lloyd, alice, tyler]. It was subtle in the directions, but that seems to be what the checker is looking for but is missing in your code.
