One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade


 

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(sum(numbers)) / float(len(numbers))
    return total

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

    avrg = homework + quizzes + tests
    return avrg
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 = []
    students = [ "lloyd", "alice", "tyler"]
    for student in students:
        results.append(get_average(students))
    return average(results)
print get_class_average([students])


#2

This is a reference object that is meant to be in global scope. The items are themselves reference pointers so should not be written as strings.


#3

meaning? students = [ lloyd, alice, tyler]
it still kicks out the same error

thanks for the help its been most frustrating

#5

Yes. Write that up with you other data dictionaries.


#6

This should be student so only one data object is passed in.
