7.15 zipfile -- Work with ZIP archives

New in version 1.6.

The ZIP file format is a common archive and compression standard. This module provides tools to create, read, write, append, and list a ZIP file. Any advanced use of this module will require an understanding of the format, as defined in PKZIP Application Note.

This module does not currently handle ZIP files which have appended comments, or multi-disk ZIP files.

The available attributes of this module are:

exception error

The error raised for bad ZIP files.

class ZipFile

The class for reading and writing ZIP files. See ``ZipFile Objects'' (section 7.15.1) for constructor details.

class PyZipFile

Class for creating ZIP archives containing Python libraries.

class ZipInfo([filename[, date_time]])

Class used the represent infomation about a member of an archive. Instances of this class are returned by the getinfo() and infolist() methods of ZipFile objects. Most users of the zipfile module will not need to create these, but only use those created by this module. filename should be the full name of the archive member, and date_time should be a tuple containing six fields which describe the time of the last modification to the file; the fields are described in section 7.15.3, ``ZipInfo Objects.''

is_zipfile(filename)

Returns true if filename is a valid ZIP file based on its magic number, otherwise returns false. This module does not currently handle ZIP files which have appended comments.

ZIP_STORED

The numeric constant for an uncompressed archive member.

ZIP_DEFLATED

The numeric constant for the usual ZIP compression method. This requires the zlib module. No other compression methods are currently supported.
