(filename, mode="rb", *,
         format=None, check=-1, preset=None, filters=None,
         encoding=None, errors=None, newline=None)
Open an LZMA-compressed file in binary or text mode.

    filename can be either an actual file name (given as a str, bytes,
    or PathLike object), in which case the named file is opened, or it
    can be an existing file object to read from or write to.

    The mode argument can be "r", "rb" (default), "w", "wb", "x", "xb",
    "a", or "ab" for binary mode, or "rt", "wt", "xt", or "at" for text
    mode.

    The format, check, preset and filters arguments specify the
    compression settings, as for LZMACompressor, LZMADecompressor and
    LZMAFile.

    For binary mode, this function is equivalent to the LZMAFile
    constructor: LZMAFile(filename, mode, ...). In this case, the
    encoding, errors and newline arguments must not be provided.

    For text mode, an LZMAFile object is created, and wrapped in an
    io.TextIOWrapper instance with the specified encoding, error
    handling behavior, and line ending(s).
