This sounds like the "yield from" proposal that had discussion some months ago. Your above idiom would become: yield from g() See PEP 380: http://www.python.org/dev/peps/pep-0380/ Short answer, not available yet. A Google search on: python pep "yield from" found some implementations at activestate, such as this: http://code.activestate.com/recipes/577153-yet-another-python-implementation-of-pep-380-yield/ which lets you decorate an existing generator so that you can write: yield _from(gen()) where gen() is the decorated generator.
