Either fromString and toString, or parse and format -- be consistent:-).

And to summarize the parallel discussion on python-dev for others:

It seems the arithmetic part should be dealt by fixing the sandbox's
Decimal (just make sure rounding IS programmable...;-), but then we
can have, that one for arithmetic, AND a mixin for formatting, giving
a Money by multiple inheritance; sounds cool to me:-).

Maybe Python 2.4 WILL have some Money at long last...!-)
