Its working, but an error occurs! what is wrong here?


#1

Here is my exact 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=float(sum(numbers))
total = total/len(numbers)
return total
def get_average (student):
homework = average(student['homework'])
quizzes =average(student['quizzes'])
tests = average(student['tests'])
sum = homework*0.1 +quizzes * 0.3 + tests * 0.6
return sum

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))

def get_class_average(students):
results=[]
for s in students:
results.append(get_average(s))
return average(results)
Student = [lloyd, alice, tyler]
print get_class_average(Student)
print get_letter_grade(get_class_average(Student))

i don't see why shouldn't it work! can any body help out?

I'm not sure if you have fixed this yet, or if this is the problem, but in the get_average function, you don't have the multiplication symbols in there. Instead of this:

def get_average (student):
homework = average(student['homework'])
quizzes = average(student['quizzes'])
tests = average(student['tests'])
sum = homework * 0.1 +quizzes 0.3 + tests0 .6
return sum

I believe it should be this for the get_average function:

def get_average (student):
homework = average(student['homework'])
quizzes = average(student['quizzes'])
tests = average(student['tests'])
sum = homework * 0.1 + quizzes * 0.3 + tests *0.6
return sum

I hope this helps!

Thanks for answering but actually no it's not the issue! it was related to the copy paste problem!
