#Here is the Python code you requested.

    """Decorator for methods that apply a brick to inputs.
    Parameters
    \*args, optional
    The application method to wrap.
    \*\*kwargs, optional
    Attributes to attach to this application.
    Notes
    This decorator replaces application methods with :class:`Application`
    instances. It also sets the attributes given as keyword arguments to
    the decorator.
    Note that this decorator purposely does not wrap the original method
    using e.g. :func:`~functools.wraps` or
    :func:`~functools.update_wrapper`, since that would make the class
    impossible to pickle (see notes at :class:`Application`).
    Examples
    >>> class Foo(Brick):
    ...     @application(inputs=[\x\], outputs=[\y\])
    ...     def apply(self, x):
    ...         return x + 1
    ...     @application
    ...     def other_apply(self, x):
    ...         return x - 1
    >>> foo = Foo()
    >>> Foo.apply.inputs
    [\x\]
    >>> foo.apply.outputs
    [\y\]
    >>> Foo.other_apply # doctest: +ELLIPSIS
    <blocks.bricks.base.Application object at ...>
