This tests for generator objects, and you could also use::

   return type(v) is types.GeneratorType

I think that this is pretty direct already.

I also need to test for generator functions from time to time for which 
I use::

   def _isaGeneratorFunction(func):
       '''Check the bitmask of `func` for the magic generator flag.'''
       return bool(func.func_code.co_flags & CO_GENERATOR)
