8/9 class average - anyone know what is wrong here?


#1

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]
}
class_list=[lloyd,alice,tyler]

Add your function below!

def average(numbers):
total = 0
total = sum(numbers)
total = (float(total))/len(numbers)
return total

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

def get_letter_grade(score):
if score >=90:
return "A"
elif score>=80:
return "B"
elif score >=70:
return "C"
elif score>=60:
return "D"
else:
return "F"
get_letter_grade(get_average(lloyd))

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


#2
for x in students:
        results.append(get_average(x)) 
return average(results)

#3

I'm working on this lesson also, so am not an expert,
but in following the directions I defined the list

students =[lloyd, alice, tyler]
