Is this really backquotes, i.e., `n`?  If so it's syntactic sugar for 

s = repr(n)

which assigns to s the printable representation (a string) of n.  If
you're working at the command line then just

>>> n

will show this string, too.  If you want to customize the printed
representation of the object, you can define a method '__repr__' for
your class like this:

<transcript>
>>> class Foo:
...     def __repr__(self): return 'I\'m a foo!'
... 
>>> f = Foo()
>>> f
I'm a foo!
</transcript>

Des,
