5    :synopsis: Low-level interface to compression and decompression routines
10 For applications that require data compression, the functions in this module
11 allow compression and decompression, using the zlib library. The zlib library
29    Exception raised on compression and decompression errors.
50    *level* is an integer from ``0`` to ``9`` or ``-1`` controlling the level of compression;
51    ``1`` (Z_BEST_SPEED) is fastest and produces the least compression, ``9`` (Z_BEST_COMPRESSION)
52    is slowest and produces the most.  ``0`` (Z_NO_COMPRESSION) is no compression.
54    compromise between speed and compression (currently equivalent to level 6).
65      better compression at the expense of greater memory usage.  The
83       compression type.
87    Returns a compression object, to be used for compressing data streams that won't
90    *level* is the compression level -- an integer from ``0`` to ``9`` or ``-1``.
91    A value of ``1`` (Z_BEST_SPEED) is fastest and produces the least compression,
93    ``0`` (Z_NO_COMPRESSION) is no compression.  The default value is ``-1`` (Z_DEFAULT_COMPRESSION).
94    Z_DEFAULT_COMPRESSION represents a default compromise between speed and compression
97    *method* is the compression algorithm. Currently, the only supported value is
105    internal compression state. Valid values range from ``1`` to ``9``.
108    *strategy* is used to tune the compression algorithm. Possible values are
112    *zdict* is a predefined compression dictionary. This is a sequence of bytes
194    The *zdict* parameter specifies a predefined compression dictionary. If
208 Compression objects support the following methods:
234    Returns a copy of the compression object.  This can be used to efficiently
239    Added :func:`copy.copy` and :func:`copy.deepcopy` support to compression
249    this remains ``b""`` until the last byte that contains compression data is
