In the example, myzip is closed after the ZipFile is also a context manager and therefore supports the ZIP structures for an empty archive will be written to the file. If the file is created with mode 'w', 'x' or 'a' and thenĬlosed without adding any files to the archive, the appropriate Which will be used to decode metadata such as the names of members and ZIP When mode is 'r', metadata_encoding may be set to the name of a codec, Similar behavior occurs with files newer than ,

Zip files older than at the cost of setting the The strict_timestamps argument, when set to False, allows to When using ZIP_BZIP2 integers 1 through 9 are accepted When using ZIP_DEFLATED integers 0 through 9 are accepted When using ZIP_STORED or ZIP_LZMA it has no effect. The compresslevel parameter controls the compression level to use when If it isįalse zipfile will raise an exception when the ZIP file would Use the ZIP64 extensions when the zipfile is larger than 4 GiB. 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. Values will cause NotImplementedError to be 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
