18.7 <tt class="module">pyclbr</tt> --
         Python class browser support</A>
</H1>

<P>
<A NAME="module-pyclbr"></A>

<P>
The <tt class="module">pyclbr</tt> can be used to determine some limited information
about the classes, methods and top-level functions
defined in a module.  The information
provided is sufficient to implement a traditional three-pane class
browser.  The information is extracted from the source code rather
than by importing the module, so this module is safe to use with
untrusted source code.  This restriction makes it impossible to use
this module with modules not implemented in Python, including many
standard and optional extension modules.

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-4980' xml:id='l2h-4980' class="function">readmodule</tt></b>(</nobr></td>
  <td><var>module</var><big>[</big><var>, path</var><big>]</big><var></var>)</td></tr></table></dt>
<dd>
  Read a module and return a dictionary mapping class names to class
  descriptor objects.  The parameter <var>module</var> should be the name
  of a module as a string; it may be the name of a module within a
  package.  The <var>path</var> parameter should be a sequence, and is used
  to augment the value of <code>sys.path</code>, which is used to locate
  module source code.
</dl>

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-4981' xml:id='l2h-4981' class="function">readmodule_ex</tt></b>(</nobr></td>
  <td><var>module</var><big>[</big><var>, path</var><big>]</big><var></var>)</td></tr></table></dt>
<dd>
  Like <tt class="function">readmodule()</tt>, but the returned dictionary, in addition
  to mapping class names to class descriptor objects, also maps
  top-level function names to function descriptor objects.  Moreover, if
  the module being read is a package, the key <code>'__path__'</code> in the
  returned dictionary has as its value a list which contains the package
  search path.
