7/9 Syntax Error


#1

My code is:

def grades_variance(scores):
average = grades_average(scores)
variance = 0
for score in scores:
variance += (average - score) ** 2
total = variance / float(len(scores)
return total
print grades_variance(grades)

It throws the error:

File "python", line 24
return total
^
SyntaxError: invalid syntax

SINCE WHEN IS RETURN INVALID!?!?!? I checked my indentation over and over, so it's not that. I blame unicorns for this.

this is my code, this code run in my cpu:

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)
variance = 0
for score in scores:
variance += (average - score) ** 2 / float(len(scores))
return variance
print grades_variance(grades)
