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.
