How is Everybody Doing?

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

``````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))

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"

def get_class_average(students):
results = []
for stud in students:
results.append(get_average(stud))

return average(results)

class_avg = get_class_average([lloyd,alice,tyler])

#2

``class_avg = get_class_average([lloyd,alice,tyler])``

... you should should have this global assignment statement ...

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

... and use the `students` variable as the argument to `get_class_average`.

The assignment statement was added in Exercise 3: Put It Together, but that statement got lost later on.
