I cant figure it out


#1

type or paste c
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)
        aver = total / len(numbers)
        return aver

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


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

I cant figure it out, it keep saying:

Oops, try again. get_class_average([alice]) resulted in an error: list indices must be integers, not str


#2

What if we use a variable name that is more descriptive?

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

Recall that students is a list of dictionaries. student is one of those dictionaries.
