8. returns 91.15 instead of 85.85 as expected


#1

what is going on?

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

print get_class_average(students)

@bitwhiz36512: The segment of code you've posted seems to be correct. I'd suggest you to check the instructions and see your multiplications you're doing for homework, quizzes and tests.

i have the same problem, help pls.)

**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)/len(numbers)
return total
def get_average(student):
homework=average(student['homework'])
quizzes=average(student['quizzes'])
tests=average(student['tests'])
return 0.1*homework + \
0.3*quizzes + \
0.6*tests
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"
def get_class_average(students):
results=[]
for student in students:
results.append(get_average(student))
results=average(results)
return results**

It seems only alice went through the get_average part, but i didnt get how to fix it yet :\


#5

I got it, it was stupid.
it was :
def get_class_average(students):
....results=[]
....for s in students:
........results.append(get_average(s))
........return average(results)

it should be:
def get_class_average(students):
....results=[]
....for s in students:
........results.append(get_average(s))
....return average(results)

Thanks for sharing the fix, I was stuck on the same point, myself!

Thanks in advance :slight_smile:
