Right answer but appears to have the wrong outcome


#1

sorry the last device i did this on didn't allow me to type very well but here is my code:
grades = [100, 100, 90, 40, 80, 100, 85, 70, 90, 65, 90, 85, 50.5]

def print_grades(grades):
for grade in grades:
print grade

def grades_sum(grades):
total = 0
for grade in grades:
total += grade
return total

def grades_average(grades):
sum_of_grades = grades_sum(grades)
average = sum_of_grades / float(len(grades))
return average

def grades_variance(scores):
average = grades_average(scores)
varince = 0

for score in scores:
    variance = variance + (average-score)**2

variance = variance/len(scores)
return variance

print grades_variance(grades)

Could you please paste you code :smiley:

i found the answer, i didn't write variance correctly in one of the lines
but thanks any way
