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. �rN� c C sT t � | _d| _d| _t| _|dk r.tjdt� d| ko@dkn sNt d��|dkr`d }t }nb|dkr|d }t }t |�| _ nF|dkr�d }t }t |�| _ n*|dkr�d}t }t |�| _ nt d|f ��t|tttjf�� r�t||�| _d| _|| _n.t|d��st|d��r|| _|| _ntd��| jt k�rJtj| jttd�}tj|�| _ nd| _ dS )a> 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. 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.

The filename argument can be an actual filename (a str, bytes, or PathLike object), or an existing file object to read from or write to. The mode argument can be "r", "rb", "w", "wb", "x", "xb", "a" or "ab" for binary mode, or "rt", "wt", "xt" or "at" for text mode. The default mode is "rb", and the default compresslevel is 9. For binary mode, this function is equivalent to the BZ2File constructor: BZ2File(filename, mode, compresslevel). In this case, the encoding, errors and newline arguments must not be provided. For text mode, a BZ2File object is created, and wrapped in an io.TextIOWrapper instance with the specified encoding, error handling behavior, and line ending(s). �trI zInvalid mode: %rNz0Argument 'encoding' not supported in binary modez.Argument 'errors' not supported in binary modez/Argument 'newline' not supported in binary moder )r5 )r �replacer r- � TextIOWrapper)r2 r3 r5 �encoding�errors�newlineZbz_modeZ binary_filer7 r7 r8 r ! s c C s t |�}|j| �|j� S )z�Compress a block of data. compresslevel, if given, must be a number between 1 and 9.
