# Something is missing or broken

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

``````students = [lloyd, alice, tyler]

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]
}
def average(numbers):
total = float(sum(numbers))/len(numbers)

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests= average(student["tests"])

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:
avg = get_average(student)
results.append(avg)
return average(results)

average = get_class_average(students)
print average
print C_average``````

Python is dynamic language?
what does that mean?

suppose...

`x = 2`

x is an integer type there but when you do this..

``x ="string here"``

now x is of string type,

in same way when you wrote this..

`average = get_class_average(students)`

You overwrote your function with a number type,
Functions are objects, They belong to function class.
You need to use any other identifier name so it does not override function!

Note:
make sure you define your students dictionary after you define your dictionaries.
`students = [lloyd, alice, tyler]`
