# How is Everybody Doing?

The answer is B but error is still come out.

Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade

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]
}

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

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

``````students_score = homework + quizzes + tests
return students_score``````

``````
if score >= 90 :
print 'A'

elif score >=80 :
print 'B'

elif score >= 70 :
print 'C'

elif score >= 60 :
print 'D'

else :
print 'F'``````

def get_class_average(students):
results = []

``````for student in students:
results.append(get_average(student))

``````

get_class_average([lloyd,alice,tyler])

#2

This works:
students = [lloyd, alice, tyler]
print get_class_average(students)
