Bummer. Didn't get the right output. Why?

...

mapping.py 
TILES = ('-', ' ', '-', ' ', '-', '||',
         '_', '|', '_', '|', '_', '|', '||',
         '&', ' ', '_', ' ', '||',
         ' ', ' ', ' ', '^', ' ', '||'
)

for item in TILES:
    if item != "||":
        print(item, end="")
    else:
        print("\n")

Read this post.

:point_right: Your program is printing two newlines when you call print('\n') since print automatically prints a newline and you are telling it to print another newline in the string.

This might be confusing, but the answer is simple: By default, the print function prints a newline. So, when you pass in a newline, it prints that newline and the bonus newline the print function prints out anyway.

Replace print('\n') with print('') and you'll be good to go :smiley:

Pro tip: In Python, people use print('') so often that Python lets you pass in nothing, so print() will do the same thing.

I hope this helps :grin:

Happy coding! :tada:

The print function in Python 3 defaults to print('', end='\n') so, essentially you are telling it to print 2 new lines instead of 1. You can remove all arguments, passing only print() itself or, if you wish to be more explicit, you can keep your existing print statement but change the end argument to match your other print call.
