Oops, try again. Did you remember to print the letter grade for the class's average

83.8666666667
Traceback (most recent call last):
File "python", line 52, in
NameError: name 'results' is not defined


I feel like I am so close but I can't seem to find out what it is. It has something to do with the print functions below:

As I tweak them, I get the letter "A" and 83.8666666667


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]
}
students = [lloyd, alice, tyler]
# Add your function below!
def average(numbers):
    total = sum(numbers)
    total = float(total)
    return total / len(numbers)

def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    weight = homework * 0.1 + quizzes * 0.3 + tests * 0.6
    return weight
    
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 student in students:
        results.append(get_average(student))
    return average(results)
    
print get_class_average(students)
print get_letter_grade(average(results))

Too late! I fixed it! I was thinking about the get_average function instead of the get_class_average function. It asked for the average as a whole. Which means the get_class_average function is going to be called twice.

this code below is wrong:

print get_class_average(students) print get_letter_grade(average(results))
