This is for use primarily in marshal-type functions, when a new object needs to be created ``magically'' and not by using the regular creation functions. This module provides a low-level interface to the interpreter, so care must be exercised when using this module. <P> The <tt class="module">new</tt> module defines the following functions: <P> <dl><dt><b><a name="l2h-641"><tt class="function">instance</tt></a></b>(<var>class</var><big>[</big><var>, dict</var><big>]</big>) <dd> This function creates an instance of <var>class</var> with dictionary <var>dict</var> without calling the <tt class="method">__init__()</tt> constructor. If <var>dict</var> is omitted or <code>None</code>, a new, empty dictionary is created for the new instance. Note that there are no guarantees that the object will be in a consistent state. </dl> <P> <dl><dt><b><a name="l2h-642"><tt class="function">instancemethod</tt></a></b>(<var>function, instance, class</var>) <dd> This function will return a method object, bound to <var>instance</var>, or unbound if <var>instance</var> is <code>None</code>. <var>function</var> must be callable, and <var>instance</var> must be an instance object or <code>None</code>. </dl> <P> <dl><dt><b><a name="l2h-643"><tt class="function">function</tt></a></b>(<var>code, globals</var><big>[</big><var>, name</var><big>[</big><var>, argdefs</var><big>]</big><big>]</big>) <dd> Returns a (Python) function with the given code and globals. If <var>name</var> is given, it must be a string or <code>None</code>. If it is a string, the function will have the given name, otherwise the function name will be taken from <code><var>code</var>.co_name</code>. If <var>argdefs</var> is given, it must be a tuple and will be used to determine the default values of parameters. </dl> <P> <dl><dt><b><a name="l2h-644"><tt class="function">code</tt></a></b>(<var>argcount, nlocals, stacksize, flags, codestring, constants, names, varnames, filename, name, firstlineno, lnotab</var>) <dd> This function is an interface to the <tt class="cfunction">PyCode_New()</tt> C function. </dl> <P> <dl><dt><b><a name="l2h-645"><tt class="function">module</tt></a></b>(<var>name</var>) <dd> This function returns a new module object with name <var>name</var>. <var>name</var> must be a string. </dl> <P> <dl><dt><b><a name="l2h-646"><tt class="function">classobj</tt></a></b>(<var>name, baseclasses, dict</var>) <dd> This function returns a new class object, with name <var>name</var>, derived from <var>baseclasses</var> (which should be a tuple of classes) and with namespace <var>dict</var>. </dl> <DIV CLASS="navigation"> <p><hr> <table align="center" width="100%" cellpadding="0" cellspacing="2"> <tr> <td><A href="subclassing-reprs.html"><img src="../icons/previous.gif" border="0" height="32" alt="Previous Page" width="32"></A></td> <td><A href="python.html"><img src="../icons/up.gif" border="0" height="32" alt="Up One Level" width="32"></A></td> <td><A href="module-site.html"><img src="../icons/next.gif" border="0" height="32" alt="Next Page" width="32"></A></td> <td align="center" width="100%">Python Library Reference</td> <td><A href="contents.html"><img src="../icons/contents.gif" border="0" height="32" alt="Contents" width="32"></A></td> <td><a href="modindex.html" title="Module Index"><img src="../icons/modules.gif" border="0" height="32" alt="Module Index" width="32"></a></td> <td><A href="genindex.html"><img src="../icons/index.gif" border="0" height="32" alt="Index" width="32"></A></td> </tr></table> <b class="navlabel">Previous:</b> <a class="sectref" href="subclassing-reprs.html">3.25.2 Subclassing Repr Objects</A> <b class="navlabel">Up:</b> <a class="sectref" href="python.html">3.
