# How does Python know what I want?

#1

In the instructions in this exercise, it says You can expect `student`s to be a list containing your three students
Why is this? Why don't I need to make a list `students`?

``````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 = {

"homework": [0.0, 87.0, 75.0, 22.0],
"quizzes": [0.0, 75.0, 78.0],
"tests": [100.0, 100.0]
}

def average(numbers):
for i in numbers:
total = sum(numbers)
total = float(total)

def get_average(student):
for i in student:
homework = average(student["homework"])*0.1
quizzes = average(student["quizzes"])*0.3
tests = average(student["tests"])*0.6
return homework + quizzes + tests

if score >= 90:
return "A"
elif score >= 80:

elif score >= 70:
return "C"

return "D"

return "F"

results = []
for student in students:
results.append(get_average(student))
return average(results)``````

It doesn't. It's up to you to line everything up to get the desired result.
The instructions you are referring to are describing how your function should behave/how it will be used.
