I am lost Please give guidance


#1

the editor says: "The following is missing or broken when we tried to use it: alice, lloyd, tyler, students,
get_class_average,get_letter_grade

here is my code:
def get_average(students):
results = [ ]
for students in students:
results.append(get_average(students))
return average(results)
students = [ lloyd,alice,tyler]
print get_class_average(students)
print get_letter_grade(get_class_average(students))


#2

May I ask you to post here your whole code with a proper formatting?

There is a special icon </> to format the code in the top bar of the editor.


#3
indent preformatted text by 4 spaces

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]
}
students = [lloyd, alice, tyler]

Add your function below!

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

def get_letter_grade(score):
if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"

print get_letter_grade(get_average(lloyd))

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

return average(results)
