You might take a look at a feature of flufl.i18n, which supports automatic
substitutions from locals and globals:

http://flufli18n.readthedocs.org/en/latest/docs/using.html#substitutions-and-placeholders

In general, flufl.i18n builds on PEP 292 $-strings and gettext to support more
i18n use cases, especially in multi-language contexts.  Still, the
substitution features can be more or less used independently, and do a lot of
what you're looking for.  This feature is only supported on implementations
with sys._getframe() though (e.g. CPython).
