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

the above is my code and when i run it the following is the error,
"Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected"

can anyone tell me what is wrong. Please help me out


8. Part of the Whole - Typo in step 3
#2

your return indentation is wrong.

    for student in students :
        results.append(get_average(student))
        return average(results)

this is the code as it is with indentation, hope this will help.


#4

for student in students :
        results.append(get_average(student))
        return average(results)

return should be outside the for loop and inside the method get_class_average.


#5

Also,
results = []
shouldn't be inside the for loop:

results = []
for student in students

instead of:

for student in students:
results = []

hope this helps :slightly_smiling:


#6

thanks, that worked. thanks a lot


#7

thanks, I corrected that myself before posting the code second time. Thanks for the help.
