Oops, try again. get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected


#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]
}

Add your function below!

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

def get_average(student):
a = average(student[“homework”])
b = average(student[“quizzes”])
c = average(student[“tests”])
d = float(0.1a+ 0.3b+ 0.6*c)
return d

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”

print get_letter_grade(get_average(lloyd))

results = []

students = [lloyd,alice,tyler]

for student in students:
results.append(float(get_average(student)))

def get_class_average(students):
return average(results)

I have used this code but the error still continues.

I may need your help!!

why do you not place the results list and loop inside the function? Currently, importing or calling your multiply times will not work well
