Yes to both: learning, particularly with Jython (so one keeps using
already-known Java libraries), is quite fast -- the full benefits take
more time to develop, although even using Python less than ideally can
already be faster.  But for a company to convince itself that the
investment is small and the benefits accrue rapidly -- and keep accruing
in the long term -- can still be quite a leap of faith.
