<dd> 
  Open a ZIP file named <var>filename</var>.  The <var>mode</var> parameter
  should be <code>'r'</code> to read an existing file, <code>'w'</code> to
  truncate and write a new file, or <code>'a'</code> to append to an
  existing file.  For <var>mode</var> is <code>'a'</code> and <var>filename</var>
  refers to an existing ZIP file, then additional files are added to
  it.  If <var>filename</var> does not refer to a ZIP file, then a new ZIP
  archive is appended to the file.  This is meant for adding a ZIP
  archive to another file, such as <span class="file">python.exe</span>.  Using

<P>
<dl><dd><pre class="verbatim">
cat myzip.zip &gt;&gt; python.exe
</pre></dl>

<P>
also works, and at least <b class="program">WinZip</b> can read such files.
  <var>compression</var> is the ZIP compression method to use when writing
  the archive, and should be <tt class="constant">ZIP_STORED</tt> or
  <tt class="constant">ZIP_DEFLATED</tt>; unrecognized values will cause
  <tt class="exception">RuntimeError</tt> to be raised.  If <tt class="constant">ZIP_DEFLATED</tt>
  is specified but the <tt class='module'><a href="module-zlib.html" tppabs="http://www.python.org/doc/current/lib/module-zlib.html">zlib</a></tt> module is not avaialble,
  <tt class="exception">RuntimeError</tt> is also raised.  The default is
  <tt class="constant">ZIP_STORED</tt>. 
</dl>

<P>
<dl><dt><b><a name='l2h-1764'><tt class='method'>close</tt></a></b> ()
<dd>
  Close the archive file.  You must call <tt class="method">close()</tt> before
  exiting your program or essential records will not be written. 
</dl>

<P>
<dl><dt><b><a name='l2h-1765'><tt class='method'>getinfo</tt></a></b> (<var>name</var>)
<dd>
  Return a <tt class="class">ZipInfo</tt> object with information about the archive
  member <var>name</var>.
</dl>

<P>
<dl><dt><b><a name='l2h-1766'><tt class='method'>infolist</tt></a></b> ()
<dd>
  Return a list containing a <tt class="class">ZipInfo</tt> object for each member of
  the archive.  The objects are in the same order as their entries in
  the actual ZIP file on disk if an existing archive was opened.
</dl>

<P>
<dl><dt><b><a name='l2h-1767'><tt class='method'>namelist</tt></a></b> ()
<dd>
  Return a list of archive members by name.
</dl>

<P>
<dl><dt><b><a name='l2h-1768'><tt class='method'>printdir</tt></a></b> ()
<dd>
  Print a table of contents for the archive to <code>sys.stdout</code>.
</dl>

<P>
<dl><dt><b><a name='l2h-1769'><tt class='method'>read</tt></a></b> (<var>name</var>)
<dd>
  Return the bytes of the file in the archive.  The archive must be
  open for read or append.
</dl>

<P>
<dl><dt><b><a name='l2h-1770'><tt class='method'>testzip</tt></a></b> ()
<dd>
  Read all the files in the archive and check their CRC's.  Return the
  name of the first bad file, or else return <code>None</code>.
</dl>

<P>
<dl><dt><b><a name='l2h-1771'><tt class='method'>write</tt></a></b> (<var>filename</var><big>[</big><var>, arcname</var><big>[</big><var>,
                          compress_type</var><big>]</big><big>]</big>)
<dd>
  Write the file named <var>filename</var> to the archive, giving it the
  archive name <var>arcname</var> (by default, this will be the same as
  <var>filename</var>).  If given, <var>compress_type</var> overrides the value
  given for the <var>compression</var> parameter to the constructor for
  the new entry.  The archive must be open with mode <code>'w'</code> or
  <code>'a'</code>. 
</dl>

<P>
<dl><dt><b><a name='l2h-1772'><tt class='method'>writestr</tt></a></b> (<var>zinfo, bytes</var>)
<dd>
  Write the string <var>bytes</var> to the archive; meta-information is
  given as the <tt class="class">ZipInfo</tt> instance <var>zinfo</var>.  At least the
  filename, date, and time must be given by <var>zinfo</var>.  The archive
  must be opened with mode <code>'w'</code> or <code>'a'</code>.
</dl>

<P>
The following data attribute is also available:

<P>
<dl><dt><b><a name='l2h-1773'><tt class='member'>debug</tt></a></b>
<dd>
  The level of debug output to use.  This may be set from <code>0</code>
  (the default, no output) to <code>3</code> (the most output).  Debugging
  information is written to <code>sys.stdout</code>.
</dl>
