How is Everybody Doing?

Oops, try again. Did you remember to print the average of the class? It looks like "83.8666666667" wasn't printed.


Finally, print out the result of calling get_class_average with your students list. Your students should be [lloyd, alice, tyler].
Then, print the result of get_letter_grade for the class's average.


Replace this line with your 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)
    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 0.1 * float(homework) + 0.3 * float(quizzes) + 0.6 * float(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_letter_grade(get_average(tyler))    
print get_letter_grade(tyler)

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

Well the first thing if your indentation.

students = [lloyd ,alice ,tyler] 
print get_class_average([lloyd, alice, tyler])
print get_letter_grade(get_average(lloyd) + get_average(alice) + get_average(tyler))

This all is indented inside of the function get_class_average, so you need to unindent these three lines so that they are in line with the line

def get_class_average(students):

Besides this, the logic of your print line's is a little messed up.
On this line:
print get_class_average([lloyd, alice, tyler])
nothing is wrong, but you created the variable students just above it, so I suggest passing it the variable like

print get_class_average(students)

And in the last line:
print get_letter_grade(get_average(lloyd) + get_average(alice) + get_average(tyler))
It's the same thing. This will work fine, but you could more easily do

print get_letter_grade(get_class_average(students))

So the only thing that was stopping you from completing this lesson was your indentation, but I wanted to let you know about the students variable, and what the point of having it was. :slight_smile:
I hope this helped!

it helps a lot. the only thing that im trynig to figure out is

i still get this error
Oops, try again. Did you remember to print the letter grade for the class's average?

thanks

Oh I'm so sorry, I messed up the get_letter_grade code i showed you, I'll change it in the original post, but it should be

print get_letter_grade(get_class_average(students))

because it asks you to

print the result of get_letter_grade for the class's average.
