Add your function below!

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

student = lloyd, alice, tyler

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 >= 90.0:
return "A"
elif score >= 80.0:
return "B"
elif score >= 70.0:
return "C"
elif score >= 60.0:
return "D"
else:
return "F"

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

Could you please describe your problem.

And could you mark the whole code and click on the </> symbol so we can read your code better :slightly_smiling:

@oliver_houghton_rhs: I edited this post, noticed a few things with your code.

1 - You're trying to set three values, where each one of them is a dictionary, to the variable student (right above your get_average() function definition), poor thing, it can't handle like this!
2 - You've created another list called students but you passed as argument to your function get_class_average() as student other than students.

I could only notice those two things.

Best regards,
G4be.

Edit: According to OP and after testing it, the code works and I can't really understand how he managed to store three references to the dictionaries inside of the student variable.

there is no problem I was practicing using the forum to help my g's

worked for me :):):):):):):):):))::)):):):)):):):):):))::grin::hamburger:

True, there was no problem, my apologies.
I wonder how you stored three dictionaries inside a variable, who's not a list or anything, and it worked.

Interesting.
I'll try to find out the reason for this.

Once again, my apologies.

Best regards,
G4be.
