Part 8/9


#1

HI everyone,

I have a numertical problem as my function returns 91.15 where 81.85 is expected. I had no problems with the outcomes prior to this point so i am pritty sure the numbers are correct. So, where am I wrong and why?
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))
return total/len(numbers)
def get_average(name):
return average(name["homework"])0.1+average(name["quizzes"])0.3+average(name["tests"])*0.6

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"
print get_letter_grade(get_average(lloyd))

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

Hello,

Please consider this line

Consider doing:

    total/=(len(numbers))
    return total
