<FONT><h3>Debugger</h3>
<p>The <a NAME="idx1073742945"></a><a naME="idx1073742946"></A><Tt claSS="monofont">pdb</TT> module defines an interactive source code debugger for Python programs. You can use this tool to verify and modify variables and to set and examine breakpoints. It allows inspection of stack frames, single stepping of source lines, and code evaluation. This module is based on the module <tt class="monofont">bdb,</tt> which implements a generic Python debugger base class.</p>
<p>See <a href="227.html">Chapter 17,"Development Tools,"</a> for details.</p>
