# How is Everybody Doing?

}

student = ["lloyd","alice","tyler"]
def average(numbers):
total = sum(numbers)
total = float(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
if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
return "F"
def get_class_average(students):
results = []
for student in students:
results.append(get_average(student))
return average(results)
print student
print get_class_average([lloyd,alice,tyler])

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 am not sure what is wrong with my code，
I got result like below：
['lloyd', 'alice', 'tyler']
83.8666666667
B
None

When you call the functions you can use the already existing student list a the argument instead of creating a separate array. Otherwise you are creating the student list for nothing. Without your ode formatted, it is incredibly difficult to see what could be going wrong. Can you edit your post and put the code within the code tags so it will format correctly? At the top of the editor, it is the symbol.
Example:

``````print get_class_average(student)
