# 8/9 Part of the Whole Help

My code:

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

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

homework = homework * .1
quizzes = quizzes * .3
tests = tests * .6

total = 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"

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

Which gets me

Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected

#2

Too much indentation. The loop is not permitted to complete running. Back off this line by four spaces. It will then pass.

#3

Thanks! Worked! Funny how such a small mistake can go overseen

#4

Why this doesnt work?
def get_class_average(students):
result = []
for student in students:
result.append(get_average(student))
result = average(result)
return result

Oops, try again.
get_class_average([alice, lloyd]) resulted in an error: 'float' object has no attribute 'append'

But when I changed as follow, it works. Dont know the reason, please help.
def get_class_average(students):
result = []
for student in students:
result.append(get_average(student))
return average(result)
