# How Is Everybody Doing?

#1

When I tried to run the code it throws an error:

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

Which part/code I was wrong?

``````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)
result = total / len(numbers)

return result

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

return 0.1 * average(student["homework"]) + 0.3 * average(student["quizzes"]) + 0.6 * average(student["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):
result = []
for student in students:
result.append(get_average(student))

return average(result)

print get_class_average(students)

the students list you build in 3. put it together is missing

also, function calls execute the function so they should be outside the function (hint: indent)

#3

Never mind, I got it. My `print` part was inside the function. Now its working
