If allowZip64 is True (the default) zipfile will create ZIP files that ZIP_DEFLATED, ZIP_BZIP2 or ZIP_LZMA is specifiedīut the corresponding module ( zlib, bz2 or lzma) is notĪvailable, RuntimeError is raised.

If mode is 'r' or 'a', the file should be seekable.Ĭompression is the ZIP compression method to use when writing the archive, Mode is 'a' and the file does not exist at all, it is created. This is meant forĪdding a ZIP archive to another file (such as python.exe). ZIP file, then a new ZIP archive is appended to the file. If mode is 'a' and file refers to an existing ZIPįile, then additional files are added to it. If mode is 'x' and file refers to an existing file,

The mode parameter should be 'r' to read an existingįile, 'w' to truncate and write a new file, 'a' to append to anĮxisting file, or 'x' to exclusively create and write a new file. Open a ZIP file, where file can be a path to a file (a string), a ZipFile ( file, mode = 'r', compression = ZIP_STORED, allowZip64 = True, compresslevel = None, *, strict_timestamps = True, metadata_encoding = None ) ¶ Information about the Info-ZIP project’s ZIP archive programs and development
