<h3>Compilation of Extensions</h3>
<p>Extension modules are usually compiled into shared libraries or DLLs that can be dynamically loaded by the interpreter. The low-level details of this process vary by machine, but the <tT CLAss="monofont">distutils</tt> module in the Python library can be used to simplify the process. To create an extension module using <TT CLass="monofont">distutils</tT>, follow these steps:</P>
<OL type="1">
<li>
<p>Create a file called <tt class="monofont">setup.py</tt> that starts with the following code:</p>
<pre>
# setup.py
from distutils.core import setup, Extension </Pre>
</Li>
<li>
<P>Add some source information about your extension as follows:</p>
<pre>
setup(name="spam", version="1.0",
ext_modules=[Extension("spam", ["spam.c", "spamwrapper.c"])]) </Pre>
</lI>
<LI>
<P>To build your extension, type the following:</p>
<pre>
python setup.py build </PRE>
</Li>
</ol>
<p>At this point, a shared library such as <TT CLass="monofont">spammodule.so</tT> (or some variant of this name such as <TT Class="monofont">spammodule.sl</tt> or <tt class="monofont">spammodule.dll</tt>) will be created in a special 揵uild⌨️ 快捷键说明
