<h3 class="section">23.2 Extending <small>GDB</small> using Python</h3>
<a name="index-python-scripting"></a>
<a name="index-scripting-with-python"></a>

<p>You can extend <small>GDB</small> using the <a href="http://www.python.org/">Python programming language</a>.  This feature is available only if
<small>GDB</small> was configured using <samp>--with-python</samp>.
<small>GDB</small> can be built against either Python 2 or Python 3; which
one you have depends on this configure-time option.
</p>
<a name="index-python-directory"></a>
<p>Python scripts used by <small>GDB</small> should be installed in
<samp><var>data-directory</var>/python</samp>, where <var>data-directory</var> is
the data directory as determined at <small>GDB</small> startup (see <a href="Data-Files.html#Data-Files">Data Files</a>).
This directory, known as the <em>python directory</em>,
is automatically added to the Python Search Path in order to allow
the Python interpreter to locate all scripts installed at this location.
</p>
<p>Additionally, <small>GDB</small> commands and convenience functions which
are written in Python and are located in the
<samp><var>data-directory</var>/python/gdb/command</samp> or
<samp><var>data-directory</var>/python/gdb/function</samp> directories are
automatically imported when <small>GDB</small> starts.
