#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

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

I keep getting this error.

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],
"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 = sum(numbers)
total = float(total)
total = total/len(numbers)
return total
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

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_letter_grade(get_average(lloyd))

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

    return average(results)
