9/9 Oops, try again. One of the following is missing or broken when we tried to use it:


#1

"alice, lloyd, tyler, students, get_class_average, get_letter_grade"

The code executes and displays correct results as follows:
Lloyd 80.55
Alice 91.15
Tyler 79.9
Class Average: 83.8666666667
Class Average Grade: B
None

Here is the 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)
    avg = float(total) / len(numbers)
    return avg
    
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:
        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 x in students:
        result = get_average(x)
        print x["name"], result
        results.append(result)
#        print results
    return average(results)
    
class_students = [lloyd, alice, tyler]
class_average = get_class_average(class_students)
class_average_grade = get_letter_grade(class_average)
print "Class Average: %s" % class_average
print "Class Average Grade: %s" % class_average_grade

Any help appreciated.


#2

Solved by renaming my class_students list to students. Pedantic nit-picking of a list variable name seems to be the only sin. The original syntax and list variable name was correct and executed correctly.
