Part of the Whole - Alice is not happy with her average


#1



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

I have looked at three different posts and cannot figure out where the problem is.


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=float(sum(numbers))/len(numbers)
    return total
def get_average(student):
     homework=average(student['homework'])
     quizzes=average(student['quizzes'])
     tests=average(student['tests'])
     return .1*homework + .3*quizzes + .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'
    return get_average(lloyd)

print get_letter_grade

students=[lloyd,alice,tyler]
def get_class_average(student):
    results = []
    for student in students:
        results.append(get_average(student))
    return average(results)


#2

from the instructions:

Define a function called get_class_average that has one argument students. You can expect students to be a list containing your three students.

your argument is student, it should be students

if i would get a lower grade then i should, i wouldn't be very happy either :stuck_out_tongue:
