Give me a the Python code you requested given the following:
Complete the below
def _flattenElement(request, root, write, slotData, renderFactory, dataEscaper):

    ''''Make C{root} slightly more flat by yielding all its immediate contents as
    strings, deferreds or generators that are recursive calls to itself.
    @param request: A request object which will be passed to
    L{IRenderable.render}.
    @param root: An object to be made flatter.  This may be of type C{unicode},
    L{str}, L{slot}, L{Tag <twisted.web.template.Tag>}, L{tuple}, L{list},
    L{types.GeneratorType}, L{Deferred}, or an object that implements
    L{IRenderable}.
    @param write: A callable which will be invoked with each L{bytes} produced
    by flattening C{root}.
    @param slotData: A L{list} of L{dict} mapping L{str} slot names to data
    with which those slots will be replaced.
    @param renderFactory: If not L{None}, an object that provides
    L{IRenderable}.
    @param dataEscaper: A 1-argument callable which takes L{bytes} or
    L{unicode} and returns L{bytes}, quoted as appropriate for the
    rendering context.  This is really only one of two values:
    L{attributeEscapingDoneOutside} or L{escapeForContent}, depending on
    whether the rendering context is within an attribute or not.  See the
    explanation in L{writeWithAttributeEscaping}.
    @return: An iterator that eventually yields L{bytes} that should be written
    to the output.  However it may also yield other iterators or
    L{Deferred}s.
if it yields another iterator, the caller will iterate
    it.
if it yields a L{Deferred}, the result of that L{Deferred} will
    either be L{bytes}, in which case it\'s written, or another generator,
    in which case it is iterated.  See L{_flattenTree} for the trampoline
    that consumes said values.
    @rtype: An iterator which yields L{bytes}, L{Deferred}, and more iterators
    of the same type.'
