# printing a list of lists

i have this list of lists 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', '.', '.', '.'], ['.', '.', '.', '.', '.', '.']] and i want to print it like this : ..OO.OO.. .OOOOOOO. .OOOOOOO. ..OOOOO.. ...OOO... ....O.... i 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] my attemps: for i in range(len(grid)): for x in range(len(grid[i])): print(grid[i][x], end="") print()

In fact, i faced this question while I'm studying a book, And it asked for another way to solve this, (Hint: You will need to use a loop in a loop in order to printĀ grid[0][0], thenĀ grid[1][0], thenĀ grid[2][0], and so on, up toĀ grid[8][0]. This will finish the first row, so then print a newline. Then your program should printĀ grid[0][1], thenĀ grid[1][1], thenĀ grid[2][1], and so on. The last thing your program will print isĀ grid[8][5]. Also, remember to pass theĀ endĀ keyword argument toĀ print()Ā if you donāt want a newline printed automatically after eachĀ print()Ā call.) You also provided advance ways,and i really appreciate it. After all, all ways lead to romeš

Ala'a Aldeen Shammr mine answer code also do the same. for i in (0,5) for j in(0,8) [j][i] This goes through like this [0][0],[1][0],[2][0],.... [0][1],[1][1],[2][1]..... ................................. [0][5],[1][5],[2][5].....
