Use the zipfile module to read or write .zip files, or the higher-level functions in shutil .\n\nreads and writes gzip, bz2, compression.zstd, and lzma compressed archives if the respective modules are available.\n\n.. The following paragraph should be similar to ../includes/optional-module.rst\n\nIf any of these optional modules are missing from your copy of CPython, look for documentation from your distributor (that is, whoever provided Python to you). If you are the distributor, see optional-module-requirements.\n\nread/write support for the POSIX.1-1988 (ustar) format.\n\nread/write support for the GNU tar format including longname and longlink extensions, read-only support for all variants of the sparse extension including restoration of sparse files.\n\nread/write support for the POSIX.1-2001 (pax) format.\n\nhandles directories, regular files, hardlinks, symbolic links, fifos, character devices and block devices and is able to acquire and restore file information like timestamp, access permissions and owner.\n\nAdded support for lzma compression.\n\nArchives are extracted using a filter , which makes it possible to either limit surprising/dangerous features, or to acknowledge that they are expected and the archive is fully trusted.\n\nSet the default extraction filter to data , which disallows some dangerous features such as links to absolute paths or paths outside of the destination. Previously, the filter strategy was equivalent to fully_trusted .\n\nAdded support for Zstandard compression using compression.zstd.\n\nReturn a TarFile object for the pathname name. For detailed information on TarFile objects and the keyword arguments that are allowed, see tarfile-objects.\n\nmode has to be a string of the form 'filemode[:compression]', it defaults to 'r'. Here is a full list of mode combinations\n\nNote that 'a:gz', 'a:bz2' or 'a:xz' is not possible. If mode is not suitable to open a certain (compressed) file for reading, ReadError is raised. Use mode 'r' to avoid this. If a compression method is not supported, CompressionError is raised.\n\nIf fileobj is specified, it is used as an alternative to a file object opened in binary mode for name. It is supposed to be at position 0. …\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
