A TypeError exception is perhaps too generic for comfort in this
use case:

def deeply_mapped(func, iterable):
  for item in iterable:
    try:
      for it in flattened(item):
        yield func(it)
    except TypeError:
      yield func(item)

I'd be more confortable excepting some sort of IterationError (or
using an is_iterable function, of course). I guess there's always
itertools. ;)
