Python: how to print out a 2d list that is formatted into a grid?

Question

Currently, I have made this code

def grid_maker(h,w):
    grid = [[[\"-\"] for i in range(w)] for i in range(h)]
    grid[0][0] = [\"o\"]
    print grid

>         


        

Answer 1

Use string join()

for row in grid:
    print ''.join(*zip(*row))

or as one-liner:

print '\n'.join(''.join(*zip(*row)) for row in grid)

but if would rather recommend you to change everything into:

def grid_maker(h,w):
    grid = [["-" for _ in range(w)] for _ in range(h)]
    grid[0][0] = "o"
    return grid

print '\n'.join(''.join(row) for row in grid_maker(5,5))
