How to create a basic grid with functions

[ThomasL]

I had some spare time. How i´d do it.

def create_room(width, height, px, py):
    # fill room with dots
    room = [['.' for x in range(width+2)] for y in range(height+2)]
    # place horizontal '-'
    for i in range(width+2):
        room[0][i] = '-'
        room[height+1][i] = '-'
    # place vertical '|'
    for i in range(1, height+2):
        room[i][0] = '|'
        room[i][width+1] = '|'
    # place corners '+'
    for cy, cx in [(0, 0), (0, width+1), (height+1, 0), (height+1, width+1)]:
        room[cy][cx] = '+'
    # place player '@'
    room[py+1][px+1] = '@'
    return room

def draw(room):
    for y in range(len(room)):
        for x in range(len(room[0])):
            print(room[y][x], end='')
        print()

room = create_room(14, 8, 8, 5)
draw(room)
