Stuck on : How is everybody doing, getting the wrong Average and hence the wrong average letter grade.

'''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]
}

Add your function below!

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

return average(results)

print get_class_average(student)
print get_letter_grade(get_class_average(student))

I couldn't find a mistake in your code....have you refreshed your browser and reset the code?


#4

Yeah, still not working :-/


#5

You are missing one "s". You currently have student =[lloyd , alice , tyler] it should be students. So it should look like this: students =[lloyd , alice , tyler]

I think what @mkordik said is correct.
