    just the other way round. It returns a list of lists with the

    parameter specifies the precision (default is ``0``), the
    second the rounding method:

    - ``'common'`` rounds either up or down
    - ``'ceil'`` always rounds up
    - ``'floor'`` always rounds down

    If you don't specify a method ``'common'`` is used.

            -> 43.0
        {{ 42.55|round(1, 'floor') }}
            -> 42.5

    Note that even if rounded to 0 precision, a float is returned.  If
    you need a real integer, pipe it through `int`:

    If you for example have a list of dicts or objects that represent persons
    with `gender`, `first_name` and `last_name` attributes and you want to
    group all users by genders you can do something like the following
    snippet:

    .. sourcecode:: html+jinja

        <ul>
        {% for group in persons|groupby('gender') %}
            <li>{{ group.grouper }}<ul>
            {% for person in group.list %}
                <li>{{ person.first_name }} {{ person.last_name }}</li>
            {% endfor %}</ul></li>
        {% endfor %}
        </ul>

    Additionally it's possible to use tuple unpacking for the grouper and
    list:

    .. sourcecode:: html+jinja

        <ul>
        {% for grouper, list in persons|groupby('gender') %}
            ...
        {% endfor %}
        </ul>

    As you can see the item we're grouping by is stored in the `grouper`
    attribute and the `list` contains all the objects that have this grouper
    in common.

       attributes.  Also the `start` parameter was moved on to the right.

s�Applies a filter on a sequence of objects or looks up an attribute.
    This is useful when dealing with lists of objects but you are really
    only interested in a certain value of it.

    The basic usage is mapping on an attribute.  Imagine you have a list
    of users but you are only interested in a list of usernames:

    .. sourcecode:: jinja

        Users on this page: {{ users|map(attribute='username')|join(', ') }}

    Alternatively you can let it invoke a filter by passing the name of the
    filter and the arguments afterwards.  A good example would be applying a
    text conversion filter on a sequence:

    .. sourcecode:: jinja

        Users on this page: {{ titles|map('lower')|join(', ') }}
