9. How is Everybody doing? - Missing or Broken


#1




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


In what way am I a n00b.


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)
    total = total / len(numbers)
    return total

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"

class_list = [lloyd, alice, tyler]

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


print get_class_average(class_list)


#2

in exercise 3 you build a lists with all the students, you still have it:

class_list = [lloyd, alice, tyler]

except it should be called students, not class_list (as explained in 3. put it together)


#3

It works now. Thank You.
