Solve the following python programming problem given the following code:
@register.simple_tag(takes_context=True)
def reply_list(context, review, comment, context_type, context_id):
assistant
#Here is the Python code you requested.

    """Renders a list of comments of a specified type.
    This is a complex, confusing function accepts lots of inputs in order
    to display replies to a type of object. In each case, the replies will
    be rendered using the template :template:`reviews/review_reply.html`.
    If ``context_type`` is ``"diff_comments"``, ``"screenshot_comments"``,
    ``"general_comments"`` or ``"file_attachment_comments"``, the generated
    list of replies are to ``comment``.
    If ``context_type`` is ``"body_top"`` or ```"body_bottom"``,
    the generated list of replies are to ``review``. Depending on the
    ``context_type``, these will either be replies to the top of the
    review body or to the bottom.
    The ``context_id`` parameter has to do with the internal IDs used by
    the JavaScript code for storing and categorizing the comments.
