<p>The <a class="reference internal" href="#module-pyclbr" title="pyclbr: Supports information extraction for a Python class browser."><code class="xref py py-mod docutils literal"><span class="pre">pyclbr</span></code></a> module 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
code. This restriction makes it impossible to use this module with modules
not implemented in Python, including all standard and optional extension
modules.</p>
