Description:

def get(key, default='', delimiter=DEFAULT_TARGET_DELIM, ordered=True):
    '''
    Attempt to retrieve the named value from grains, if the named value is not
    available return the passed default. The default return is an empty string.

    The value can also represent a value in a nested dict using a ":" delimiter
    for the dict. This means that if a dict in grains looks like this::

        {'pkg': {'apache': 'httpd'}}

    To retrieve the value associated with the apache key in the pkg dict this
    key can be passed::

        pkg:apache


    :param delimiter:
        Specify an alternate delimiter to use when traversing a nested dict.
        This is useful for when the desired key contains a colon. See CLI
        example below for usage.

        .. versionadded:: 2014.7.0

    :param ordered:
        Outputs an ordered dict if applicable (default: True)

        .. versionadded:: 2016.11.0

    CLI Example:

    .. code-block:: bash

        salt '*' grains.get pkg:apache
        salt '*' grains.get abc::def|ghi delimiter='|'
    '''
    if ordered is True:
        grains = __grains__
    else:
        grains = salt.utils.json.loads(salt.utils.json.dumps(__grains__))
    return salt.utils.data.traverse_dict_and_list(
        grains,
        key,
        default,
        delimiter)
