 In the case of {}-formatting, you can specify formatting flags by placing them
 after the attribute name, separated from it with a colon. For example: a

+placeholder of ``{msecs:03.0f}`` would format a millisecond value of ``4`` as
 ``004``. Refer to the :meth:`str.format` documentation for full details on
