# 8.Part of the whole

#1

This is literally killing me. I have looked through all the other solutions and still cant get this to work. Can anyone see something i have missed

``````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):
sum(numbers)
total = float(sum(numbers))

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
return sum([homework *0.1, quizzes *0.3, tests *0.6])

score=float(score)
if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >=70:
return "C"
elif score >=60:
return "D"
else:
return "F"
def get_class_average(students):
results = []
for student in students:
results.append(get_average(student))
return average(results)``````

#2

This line should not be necessary. `score` is a float already (or should be).

From the looks of it, the `students` list is missing.

``students = [ lloyd, alice, tyler ]``

#3

Nope, that doesn't work.

The code in post #1 will return the average returns the wrong output.

#4

This line is not needed, and is not a statement. It may be removed.

#6
`````` def get_class_average(students):
results = []
for student in students:
results.append(get_average(student))
return average(results)`

Indent error``````
