Not sure why this is not passing

is there something wrong with my code?

mapping.py 
TILES = ('-', ' ', '-', ' ', '-', '||',
         '_', '|', '_', '|', '_', '|', '||',
         '&', ' ', '_', ' ', '||',
         ' ', ' ', ' ', '^', ' ', '||'
)
for tile in TILES:
    line_end = ""
    if tile == '||':
        line_end="\n"
        print(line_end)
    else:
        print(tile, end=line_end)

SungJin Kim - There seems to be a pretty consistent amount of confusion related to the print() function implemented with Python3, especially with this Challenge in particular. Even I had some issue with it initially, but it seems to stem from a misunderstanding about how print() was implemented (see docs) within Python and what the Challenge asks for. The function, print(), is described as defaulting to end='\n', meaning that, if left unchanged, each time the print() is called, regardless of content, it will automatically print at least that one newline. Your code basically amounts to print('\n', end='\n') in your if-conditional, so you're printing 2 lines rather than the 1 it asks for in the Challenge task. You should be able to figure out a solution that works for you, but if you still don't quite grasp it, feel free to let me know :)
