Multidimensional list in python...

I cannot seem to loop through printing out the values of the grid in python using a multidimensional list.

Here is my code;

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

for i in range(0,len(grid),1):
    for j in range(0,len(grid[i]),1):
        if j == (i + 5):
            print(grid[i][j])
        else:
            print(grid[i][j],end=' ')

At the moment the result I get is this;

. . . . . .
. 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 . . . . . . . . .

It seems to print out the top line fine but not the others!

Edit:

Manage to sort it out. Was getting confused how to print a new line;

I needed to be using a print() after my inner for loop like so.

for i in range(len(grid)):
    for j in range(len(grid[i])):
        print(grid[i][j],end= ' ')
    print()

Yes I think I get what you are doing, thanks. I'm gonna look at it again, just cause I'm fascinated.

Hi Mayur, I'm not really sure what you are trying to accomplish, but I was fascinated by your code. I probably can't be real helpful, but here's what I noticed. You said it only prints the top line, but it looks to me like all the information is there...but it's on one line. I'm wondering if it's your use of end="", which is intended to put things all on one line. I hope you post when you have this doing what you intended, I'd like to see haw it works.

Hi John,

I want to loop through printing each coordinate like a multidimensional array in js. For example;

0,0 | 0,1 | 0,2
1,0, | 1,1 | 1,2

But instead of the location the value at those points. Hope this makes more sense?
