Print each item on the same line unless the item is a double pipe (||). In that case, instead of printing the item, prin

Can you tell me what I am doing wrong.


TILES = ('-', ' ', '-', ' ', '-', '||',
         '_', '|', '_', '|', '_', '|', '||',
         '&', ' ', '_', ' ', '||',
         ' ', ' ', ' ', '^', ' ', '||'
for items in TILES:
    x = ||
    if items = x:
         output = tile.format("\n")
                output = tile.format(items)
            print(output, end+items)

The values in TILES are strings. Each item is closed in ' '. If you want x to check for the double pipe then set x='||'

x = '||'

later you call format on tile but I don't see where tile is created, so this would throw an error

HINT: When using print() it will automatically start a new line, unless you give it an extra parameter called end. If you set end = "" there will be no line return.

some_list = ['P', 'y', 't', 'h', 'o', 'n']
# default printing includes line return
for item in some_list:
# use optional end parameter
for item in some_list:
    print(item, end="")
>>> some_list = ['P', 'y', 't', 'h', 'o', 'n']
>>> for item in some_list:
...     print(item)

>>> for item in some_list:
...     print(item, end="")
