(Note that in the first example, one space between each column was added by the
way :func:`print` works: it always adds spaces between its arguments.)
This example demonstrates the :meth:`rjust` method of string objects, which
right-justifies a string in a field of a given width by padding it with spaces
on the left. There are similar methods :meth:`ljust` and :meth:`center`. These
methods do not write anything, they just return a new string. If the input
string is too long, they don't truncate it, but return it unchanged; this will
mess up your column lay-out but that's usually better than the alternative,
which would be lying about a value. (If you really want truncation you can
always add a slice operation, as in ``x.ljust(n)[:n]``.)
There is another method, :meth:`zfill`, which pads a numeric string on the left
with zeros. It understands about plus and minus signs::
