#2

for student in class:
thats wrong, should be for student in students and now that I am checking should be def get_class_average(student**s**)

#3

I chect it, and the following is not right too... it tells me that the answer is not right.

``````students=[lloyd,
alice,
tyler
]

def get_class_average(student):
results=[]
for student in students:
get_average(student)
results.append(get_average(student))
return average(results)``````

#4

I change it like following... who can kindly help me pointing the faluts?

running wrong...

`Oops, try again. get_class_average([alice]) returned 80.55 instead of 91.15 as expected`

``````lloyd = {

#5

your code is fine but there is a small problem with the indentation when you returning the average(results) in for loop

so just check the indentation

#6

I keep getting this error.
''' 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'''

The code works on my IDLE but not on codeacademy. What am I doing wrong? '''

i have the same problem : 91.15 instead of 85.55
code :

lloyd = {
"name": "Lloyd",
"homework": [90.0, 97.0, 75.0, 92.0],
"quizzes": [88.0, 40.0, 94.0],

}
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]
}

def average(numbers):
total = sum(numbers)
total = float(total)
total = total/len(numbers)
def get_average(student):
homework= average(student["homework"])
quizzes= average(student["quizzes"])
tests= average(student["tests"])
a = 0.1 * homework
b = 0.3 * quizzes
c = 0.6 * tests
stud_score = a + b + c

``return stud_score``

if score >= 90 :
return"A"
elif score >= 80 :
return "B"
elif score >= 70 :
return"C"
elif score >= 60 :
return "D"
else:
return "F"
``    return average(results)``
