# Sending a letter. Didn't work, then randomly it did... In case you need it

Problem1.

mentioned by @mb13

problem 2.

get_average function takes a list not dictionary as argument.

by passing **lloyd**, you are passing dictionary in it and thus it throws an error.

hint**

Comment out that line of code , do reply if it worked or not.

**greentreemee**#6

Sometimes Its useful to not mention all possible errors as it become spoon feeding and author will have nothing new to learn!

I have some problem get letter grade don't work and I don't know why

lloyd = {

# Add your function below!

return result

def get_average(student):

return score

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_average(lloyd)

print get_average(alice)

print get_average(tyler)

print get_letter_grade(lloyd)

By passing student's name you're passing dictionary to it but it needs a number(score).

Because the score can be calculated using `get_average()`

function..

You have to pass`get_average(students name)`

to `get_letter_average()`

to get the grade,

I hope it helps!

.

thank you very much, and I solve my problem.

def average(numbers):

total = sum(numbers)

result = float(total)/len(numbers)

return result

def get_average(student):

homework = average(student["homework"])

quizzes = average(student["quizzes"])

tests = average(student["tests"])

score = 0.1*average(student["homework"])+0.3*average(student["quizzes"])+0.6*average(student["tests"])

return score

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_average(lloyd)

print get_average(alice)

print get_average(tyler)

print get_letter_grade(get_average(lloyd))

Hey, glad it worked but posting answer will increase copy pasting of code(others can cheat) so you can just delete the code(by editing)

keep up the good work
