If filename is a str or bytes 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 or bytes 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.
