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

I have resolved it. I am just sharing to state that all these variable or functions need to be stated to pass the test. Putting in list form:

alice

lloyd

tyler

students

get_class_average

get_letter_grade

Most people will missed out the students variable as it has been removed after exercise 5

```
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!

return grade
def get_letter_grade(score):

elif score>=80:
return "B"
elif score>=70:
return "C"
elif score>=60:
return "D"
else:

print get_letter_grade(get_average(lloyd))

return mean
