| 56 | 3.29 <tt class="module">new</tt> -- | |
| 57 | Creation of runtime internal objects</A> | |

| 62 | ||
| 63 | <P> | |
| 64 | The <tt class="module">new</tt> module allows an interface to the interpreter object | |
| 65 | creation functions. This is for use primarily in marshal-type functions, | |
| 66 | when a new object needs to be created ``magically'' and not by using the | |
| 67 | regular creation functions. This module provides a low-level interface | |
| 68 | to the interpreter, so care must be exercised when using this module. | |
| 69 | It is possible to supply non-sensical arguments which crash the | |
| 70 | interpreter when the object is used. | |
| 71 | ||
| 72 | <P> | |
| 73 | The <tt class="module">new</tt> module defines the following functions: | |
| 74 | ||

| 79 | <dd> | |
| 80 | This function creates an instance of <var>class</var> with dictionary | |
| 81 | <var>dict</var> without calling the <tt class="method">__init__()</tt> constructor. If | |
| 82 | <var>dict</var> is omitted or <code>None</code>, a new, empty dictionary is | |
| 83 | created for the new instance. Note that there are no guarantees that | |
| 84 | the object will be in a consistent state. | |

| 105 | name will be taken from <code><var>code</var>.co_name</code>. If | |
