pressobj() - Compression compatible with gzip - Python 3.10.2 documentation Z_DEFAULT_COMPRESSION represents a default compromise between speed and compression (currently equivalent to level 6). The default value is -1 (Z_DEFAULT_COMPRESSION). A value of 1 (Z_BEST_SPEED) is fastest and produces the least compression, while a value of 9 (Z_BEST_COMPRESSION) is slowest and produces the most. Level is the compression level – an integer from 0 to 9 or -1. zipfile.ZIP_DEFLATED: Usual ZIP compressionįor ZIP_DEFLATED, the compression level compresslevel corresponds to the level of pressobj().zipfile.ZIP_STORED: No compression (default).The compression method compression is as follows BZIP2 and LZMA have a higher compression ratio, but it takes longer to compress. In write mode, you can also specify the compression method and level with the parameters compression and compresslevel. With zipfile.ZipFile(), specify the path of a newly created ZIP file as the first parameter file, and set the second parameter mode to 'w' (write). To compress individual files into a ZIP file, create a new ZipFile object and add the files you want to compress with the write() method. Compress individual files into a ZIP file Specific examples are described in the following sections. Input and Output - Reading and Writing Files - Python 3.10.2 documentation The usage is similar to reading and writing files with the built-in function open(), such as specifying the mode and using the with statement. The ZipFile object needs to be closed with the close() method, but if you use the with statement, it is closed automatically when the block is finished. ZipFile objects are created by specifying the first parameter file (path of a ZIP file) and the second parameter mode (read 'r', write 'w', append 'a', etc.) to the constructor zipfile.ZipFile().

zipfile - ZipFile Objects - Work with ZIP archives - Python 3.10.2 documentation.The zipfile module provides the ZipFile class to create, read, write, append, and list a ZIP file. Basics of the zipfile module: ZipFile objects
