What is wrong with my code?


#1

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

@s92,

You should format your code when you post it, so that we can see its indentation and other details. See How do I format code in my posts?.

The first statement within your grades_variance function is ...

average = grades_variance(scores)

The function calls itself. Is this what you intended?

It seems to work by otherwise, so there is something wrong in your intendation. Remember to print grades_variance() outside the function.
