68The ZIP file format is a common archive and compression standard.
69This module provides tools to create, read, write, append, and list a
70ZIP file. Any advanced use of this module will require an
71understanding of the format, as defined in
72<em class="citetitle"><a

74 title="PKZIP Application

80This module does not currently handle ZIP files which have appended
81comments, or multi-disk ZIP files.

112 Class used to represent information about a member of an archive.
113 Instances of this class are returned by the <tt class="method">getinfo()</tt> and
114 <tt class="method">infolist()</tt> methods of <tt class="class">ZipFile</tt> objects. Most users
115 of the <tt class="module">zipfile</tt> module will not need to create these, but
116 only use those created by this module.
117 <var>filename</var> should be the full name of the archive member, and
118 <var>date_time</var> should be a tuple containing six fields which
119 describe the time of the last modification to the file; the fields
120 are described in section <A href="zipinfo-objects.html#zipinfo-objects">7.18.3</A>, ``ZipInfo Objects.''
