Hello,
I'm super new to Python and needing some direction for a school assignment.

I have a sample grid value:

grid = [['.', '.', '.', '.', '.', '.'],
        ['.', 'O', 'O', '.', '.', '.'],
        ['O', 'O', 'O', 'O', '.', '.'],
        ['O', 'O', 'O', 'O', 'O', '.'],
        ['.', 'O', 'O', 'O', 'O', 'O'],
        ['O', 'O', 'O', 'O', 'O', '.'],
        ['O', 'O', 'O', 'O', '.', '.'],
        ['.', 'O', 'O', '.', '.', '.'],
        ['.', '.', '.', '.', '.', '.']]

- - 
This is the output I need to achieve:

..OO.OO..
.OOOOOOO.
.OOOOOOO.
..OOOOO..
...OOO...
....O....

What I have tried:

in checking for some examples i have seen code such as:

<pre>for row in grid:
    for col in row:
        print(col, end='\t')

but its wrong for the desired output. i also saw some reference to using grid[0][0],  and looping from there but im still lost on how to properly use the loop in this case. any guidance is appreciated, ty

Try this:
Python
grid = [['.', '.', '.', '.', '.', '.'],
        ['.', 'O', 'O', '.', '.', '.'],
        ['O', 'O', 'O', 'O', '.', '.'],
        ['O', 'O', 'O', 'O', 'O', '.'],
        ['.', 'O', 'O', 'O', 'O', 'O'],
        ['O', 'O', 'O', 'O', 'O', '.'],
        ['O', 'O', 'O', 'O', '.', '.'],
        ['.', 'O', 'O', '.', '.', '.'],
        ['.', '.', '.', '.', '.', '.']]
rotated = [list(reversed(x)) for x in zip(*grid)]
for row in rotated:
    for col in row:
        print(col, end='')
    print()
Now you only have one problem: finding out how it works before you hand it in! :D
