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

likes talking to the command line.
