Hi everyone,

I keep getting errors on exercise for in the graded assessment. I tried exhaustively but cant seem to find what I am doing wrong. Could someone please advise.
Forever grateful!
You can find my code and error below.

hi @Fredericvdc

You seem to have edited the grade cell which you werent suppose to do. I also see the markers ###START YOUR CODE HERE AND END YOUR CODE HERE### are removed which might cause you submission failure.

Now comes to your code

you have removed to important codes line in the I loop after get the name of feature ‘i’, you are suppose to get the data of feature ‘i’

Same way in the for loop for j column, after get the name of feature ‘j’, you are suppose to get the data of feature ‘j’

other codes are correct. so the best advise is to get a fresh copy of assignment and only mentioned codes between the assigned markers ###START AND END CODE HERE### without editing, deleting it adding anything other than what instructions are already given when you open your assignment notebook.

Regards
