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 homework*0.1 + quizzes*0.3 +tests*0.6
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"

def get_class_average(students):
students = [alice, lloyd, tyler]
results = []
for student in students:
result = get_average(student)
results.append(result)
return average(results)

ıt gives this type of error So i cannot solve that.Where is my wrong Oops, try again. get_class_average([lloyd]) returned 91.15 instead of 80.55 as expected

``Replace this line with your code.``

#2

first line of your get class average function, you overwrite your function parameter, why?

#3

i think that ı need to defıne what is the students?

#4

the great thing about functions is that we can call them multiply times:

``````print get_class_average([alice])
print get_class_average([alice, lloyd])
print get_class_average([alice, lloyd, tyler])``````

to calculate the class average of any size.

function parameters are placeholders till you supply a value when calling the function

so don't overwrite the function parameter.
