A BZ2File can act as a wrapper for an existing file object, or refer directly to a named file on disk. Note that BZ2File provides a *binary* file interface - data read is returned as bytes, and data to be written should be given as bytes. �r� c C sT t � | _d| _d| _t| _|tk r2tjdt dd� d| krFdksPn t d��|d krbd }t}nb|dkr~d}t}t |�| _nF|d kr�d}t}t |�| _n*|dkr�d}t}t |�| _nt d|f ��t|tttjf�r�t||�| _d| _|| _n.t|d��st|d��r|| _|| _ntd��| jtk�rJtj| jttd�}t�|�| _nd| _dS )aO Open a bzip2-compressed file. If filename is a str, bytes, or PathLike object, it gives the name of the file to be opened. Otherwise, it should be a file object, which will be used to read or write the compressed data. mode can be 'r' for reading (default), 'w' for (over)writing, 'x' for creating exclusively, or 'a' for appending. These can equivalently be given as 'rb', 'wb', 'xb', and 'ab'. buffering is ignored since Python 3.0. Its use is deprecated. If mode is 'w', 'x' or 'a', compresslevel can be a number between 1 and 9 specifying the level of compression: 1 produces the least compression, and 9 (default) produces the most compression. If mode is 'r', the input file may be the concatenation of multiple compressed streams.
