Character Picture Grid:
Say you have a list of lists where each value in the inner lists is a one-character
string, like this:

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', '.', '.', '.'],
        ['.', '.', '.', '.', '.', '.']]

You can think of grid[x][y] as being the character at the x- and
y-coordinates of a “picture” drawn with text characters. The (0, 0) origin
will be in the upper-left corner, the x-coordinates increase going right,
and w the y-coordinates increase going down.
Copy the previous grid value, and write code that uses it to print the image.

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

Hint: You will need to use a loop in a loop in order to print grid[0][0],
then grid[1][0], then grid[2][0], and so on, up to grid[8][0]. This will finish the first row, so then print a newline. Then your program should print
grid[0][1], then grid[1][1], then grid[2][1], and so on. The last thing your
program will print is grid[8][5].
Also, remember to pass the end keyword argument to print() if you
don’t want a newline printed automatically after each print() call.
