I'll probably get blasted for this by Python gurus... but, I've used
it with some success.  You can do

exec(myObjc + " = " + value)

or, if it's a class instance you want to create

exec(myObjc + " = " + bar + "()").

Toss whatever variables you want sent on to the instance inside "("
and ")" and you're homefree.

Unless there's some problem with that that an old-timer spots that I
haven't yet.
