No matter what I do I get back "List indices must be integers or slices, not list"

[Radical]

It returns what I expected. "y" is a list with 6 strings inside. I figured that it would loop through the items in "y" the same way it looped through the different lists in "grid".

UPDATE: Wait..... you're right. Okay I got my code to work. The solution was:

for y in grid:
    for x in y:
        print(x, end = '')
    print('')

Thank you :3
