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

>

If you want to "pretty" print your grid with each sublist on its own line, you can use pprint:

>>> grid=[[['o'], ['-'], ['-'], ['-'], ['-']], [['-'], ['-'], ['-'], ['-'], ['-']], [['-'], ['-'], ['-'], ['-'], ['-']]]

>>> from pprint import pprint
>>> pprint(grid)

[[['o'], ['-'], ['-'], ['-'], ['-']],
 [['-'], ['-'], ['-'], ['-'], ['-']],
 [['-'], ['-'], ['-'], ['-'], ['-']]]

It will still show each element as a list, as you defined it, if you want to show them as strings you'll have to use joins like m.wasowski suggests.
