Can you provide a the Python code you requested given the following:
Complete the below
def _preprocess_data(replace_names=None, replace_all_args=False, label_namer=None, positional_parameter_names=None):

    ''''A decorator to add a \'data\' kwarg to any a function.  The signature
    of the input function must include the ax argument at the first position ::
    def foo(ax, *args, **kwargs)
    so this is suitable for use with Axes methods.
    Parameters
    replace_names : list of strings, optional, default: None
    The list of parameter names which arguments should be replaced by
    `data[name]`. If None, all arguments are replaced if they are
    included in `data`.
    replace_all_args : bool, default: False
    If True, all arguments in *args get replaced, even if they are not
    in replace_names.
    label_namer : string, optional, default: None
    The name of the parameter which argument should be used as label, if
    label is not set. If None, the label keyword argument is not set.
    positional_parameter_names : list of strings or callable, optional
    The full list of positional parameter names (excluding an explicit
    `ax`/\'self\' argument at the first place and including all possible
    positional parameter in `*args`), in the right order. Can also include
    all other keyword parameter. Only needed if the wrapped function does
    contain `*args` and (replace_names is not None or replace_all_args is
    False). If it is a callable, it will be called with the actual
    tuple of *args and the data and should return a list like
    above.
    NOTE: callables should only be used when the names and order of *args
    can only be determined at runtime. Please use list of names
    when the order and names of *args is clear before runtime!
    .. note:: decorator also converts MappingView input data to list.'
