8. Part of the Whole 'float' object has no attribute


#1




get_class_average([alice]) resulted in an error: 'float' object has no attribute 'getitem'


I'm assuming it has to do with the fact that it calls get_class_average([alice]) instead of get_class_average(alice) but I have no clue as to how I should go about changing this.


The code is as follows: 

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 = 0
    total += sum(numbers)
    return float(total) / len(numbers) 

def get_average(student):
    homework = average(student["homework"]) 
    quizzes = average(student["quizzes"]) 
    tests = average(student["tests"]) 
    return homework * .10 + quizzes * .30 + \
    tests * .60

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))

students = [lloyd, alice, tyler]

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

from the instructions:

Finally, return the result of calling average() with results

you return the result of calling get_class_average with results.

Wow. I think I might be done coding for the day that answer made me feel so stupid. :joy: Thank you so much though!
