I noticed that I haven't finished writing all the code according to the Instructions and the Lesson is validated.(I clicked Save&Submit after each line code to see what it does)
My question is: code is verified line by line from current line to next line or is taking into consideration the code mentioned above?
As print grades_variance(grades) and print grades_std_deviation(grades) are mentioned earlier.This is the reason why the lesson is validated?
Or is a Python - Codecademy learning issue?
