Signature de la fonction read_orc

def read_orc(path: Union[ForwardRef('PathLike[str]'), str, IO[~T], io.RawIOBase, io.BufferedIOBase, io.TextIOBase, _io.TextIOWrapper, mmap.mmap], columns: Optional[List[str]] = None, **kwargs) -> 'DataFrame' 

Description

read_orc.__doc__

    Load an ORC object from the file path, returning a DataFrame.

    .. versionadded:: 1.0.0

    Parameters
    ----------
    path : str, path object or file-like object
        Any valid string path is acceptable. The string could be a URL. Valid
        URL schemes include http, ftp, s3, and file. For file URLs, a host is
        expected. A local file could be:
        ``file://localhost/path/to/table.orc``.

        If you want to pass in a path object, pandas accepts any
        ``os.PathLike``.

        By file-like object, we refer to objects with a ``read()`` method,
        such as a file handle (e.g. via builtin ``open`` function)
        or ``StringIO``.
    columns : list, default None
        If not None, only these columns will be read from the file.
    **kwargs
        Any additional kwargs are passed to pyarrow.

    Returns
    -------
    DataFrame
