# 8. Part of the whole

get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected

The function takes only 1 argument, instead of two.

It should take two arguments.

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 *= 0.1
quizzes *= 0.3
tests *= 0.6

return homework + quizzes + tests

if score >= 90:
return "A"
elif score >= 80 and score < 90:
return "B"
elif score >= 70 and score < 80:
return "C"
elif score >= 60 and score < 70:
return "D"
else:
return "F"

print get_average(lloyd)
print get_average(alice)
print get_average(tyler)

students = [lloyd, alice, tyler]

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

#2

Inside the for block, should be one scope up.

#3

I receive a syntax error when i put it inside the " )) "

File "python", line 61
return average(results)
^
SyntaxError: invalid syntax

#4

Move the return statement down a line so the )) belongs to the line above.

results.append(get_average(student))
