#2

It simply means that get_letter_grade() function isn't available in global scope!
how to solve it?
Fix the indentation ! currently its inside get_average() function as a local object.
To a object to be global it should have 0 - indentation .


#3

Remove the indent, you've nested it inside get_average() so it's not accessible outside of that function.

A very silly mistake, but thanks it worked.
