Total for Alice is wrong?


#1

I'm doing the Student Becomes The Teacher exercise.
https://www.codecademy.com/courses/python-beginner-en-qzsCL/1/4?curriculum_id=4f89dab3d788890003000096

I keep getting an error stating the total for Alice is coming out at 79.9 rather than 91.15 as it's supposed to be. I've verified the numbers I am using, and they are correct. I calculated by hand and I get 91.15. The 79.9 is the total for Tyler, below Alice. I've tried swapping Tyler's and Alice's numbers, but the computer catches it.

Here is 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]
}

# Add your function below!
def average(numbers):
    total = sum(numbers)
    print total
    total = float(total)
    print total
    ave = total/len(numbers)
    print ave
    return ave
    
def get_average(student):
    return (0.1 * average(student["homework"])) + \
    (0.3 * average(student["quizzes"])) + \
    (0.6 * average(student["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 = []
    results.append(get_average(student))
    return average(results)

Please help!

That line needs to be inside a loop.

Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected
can you tell me why?
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)
total = float(total)
x = total/len(numbers)
return x
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 >= 90.0:
return 'A'
elif score >= 80.0:
return 'B'
elif score >=70.0:
return 'C'
elif score >=60.0:
return 'D'
else:
return 'F'
def get_class_average(students):
results = []
for student in students:
s = get_average(student)
results.append(s)
return average(results)

This would appear to be due to the return having too much indentation (is inside the loop).
