end argument

i'm stuck at this point and how do i use the end argument to complete my code?

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

The end argument can be changed using end= followed by the new value.

By default, end is a newline (\n), but you can change it.

In this challenge, you're supposed to loop through the tiles, and if the tile is a "||", print a newline. (Note that Python by default prints a newline, so you can—and should—say print() instead of print('\n'). The second snippet prints two newlines, because Python has the end argument be \n as well!)

If the tile is not "||", you print out the tile, with the end argument being '' (an empty string). Thus Python doesn't put any end after the printing, so the tiles are all printed on the same line.

for i in TILES:
    if i == "||":
        print()
    else:
        print(i, end='')
