# FAQ: Learn Python: Student Becomes the Teacher - Part of the Whole

how do I print the result?

These are the instructions:
Define a function called `get_class_average` that has one argument `class_list` . You can expect `class_list` to be a list containing your three students.
First, make an empty list called `results` .
For each `student` item in the `class_list` , calculate `get_average(student)` and then call `results.append()` with that result.
Finally, return the result of calling `average()` with `results` .

As you can see from my code, I already completed the first two steps:
loyd = {

“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]

}

def average(numbers):

total = sum(numbers)

total = float(total)

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

if score >= 90:

``````return "A"
``````

elif score >= 80:

``````return "B"
``````

elif score >= 70:

``````return "C"
``````

elif score >= 60:

``````return "D"
``````

else:

``````return "F"
``````

If `class_list` is written as a parameter in a function definition then it is locally declared and would have no role outside of the function, let alone outside of the exercise. Parameters are variables with local scope only.
