Thank you , the imgs list defined in the earlier segment is not getting recognized by the grader , I used the input parameter’s len() and it passed now.
I am having the same problem, but I do not understand your response. I got “All tests passed” for every exercise, but a grade of 0/20 on each. Could you elaborate on the action “I used the input parameter’s len()”.
Thanks.
I finally passed. I was referencing imgs_flatten inside a function without passing it into that function, as far as I can tell. I didn’t get a perfect score, but can I keep working on the programming assignment even though I passed?
