<p>The <a class="reference internal" href="#module-new" title="new: Interface to the creation of runtime implementation objects. (deprecated)"><code class="xref py py-mod docutils literal notranslate"><span class="pre">new</span></code></a> module allows an interface to the interpreter object creation
functions. 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. It is possible to supply
non-sensical arguments which crash the interpreter when the object is used.</p>
<p>The <a class="reference internal" href="#module-new" title="new: Interface to the creation of runtime implementation objects. (deprecated)"><code class="xref py py-mod docutils literal notranslate"><span class="pre">new</span></code></a> module defines the following functions:</p>
