Repeated Capabilities
=====================

    Repeated capabilities attributes are used to set the `channel_string` parameter to the
    underlying driver function call. This can be the actual function based on the :py:class:`Session`
    method being called, or it can be the appropriate Get/Set Attribute function, such as :c:`niDCPower_SetAttributeViInt32()`.

    Repeated capabilities attributes use the indexing operator :python:`[]` to indicate the repeated capabilities.
    The parameter can be a string, list, tuple, or slice (range). Each element of those can be a string or
    an integer. If it is a string, you can indicate a range using the same format as the driver: :python:`'0-2'` or
    :python:`'0:2'`

    Some repeated capabilities use a prefix before the number and this is optional

channels
--------

    .. py:attribute:: nidcpower.Session.channels[]

        .. code:: python

            session.channels['0-2'].channel_enabled = True

        passes a string of :python:`'0, 1, 2'` to the set attribute function.


instruments
-----------

    .. py:attribute:: nidcpower.Session.instruments[]

        .. code:: python

            session.instruments['0-2'].channel_enabled = True

        passes a string of :python:`'0, 1, 2'` to the set attribute function.
