6/9, code will not work: get_average(alice) returned 128.35 instead of the expected 91.15


#1

This is what my code looks like: 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):
return (0.1 * average(student["homework"]) + 0.3 * average(student["quizzes"]) + average(student["tests"]))

Thanks for help :smile:

i have completed it now, using a different layout.


#3

what did you do to get the answer? like how did you change it and what does the finished code look like?


#4

Hi,

Here you are:
return (0.1 * average(student["homework"]) + 0.3 * average(student["quizzes"]) + 0.6 * average(student["tests"]))

High five!


#5

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 * .1) + (quizzes * .3) + (tests * .6)

:smile: high five :stuck_out_tongue:

Following is the code which works fine

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]
}

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 * .1) + (quizzes * .3) + (tests * .6)

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"

get_letter_grade(get_average(lloyd))
get_letter_grade(get_average(alice))
get_letter_grade(get_average(tyler))

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

I don't really understand why this works. Is 'average' built in to Python?

Hi Alexander,

Sorry but I can't find this exercise in new layout.
Codecademy made changes few weeks ago.
Now almost everything looks different.

If you have a problem then open new topic and ask for help.
Maybe I will help you

hax.
