<p><strong>Source code:</strong> <a class="reference external" href="https://github.com/python/cpython/tree/3.7/Lib/pyclbr.py">Lib/pyclbr.py</a></p>
<hr class="docutils" />
<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 notranslate"><span class="pre">pyclbr</span></code></a> module provides limited information about the
functions, classes, and methods defined in a Python-coded module. The
information is sufficient to implement a module browser. The
information is extracted from the Python 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>
<dl class="function">

<dd><p>Return a dictionary mapping module-level class names to class
descriptors. If possible, descriptors for imported base classes are
included. Parameter <em>module</em> is a string with the name of the module
to read; it may be the name of a module within a package. If given,
<em>path</em> is a sequence of directory paths prepended to <code class="docutils literal notranslate"><span class="pre">sys.path</span></code>,

module-level function and class names to their descriptors. Nested
objects are entered into the children dictionary of their parent. As
with readmodule, <em>module</em> names the module to be read and <em>path</em> is
prepended to sys.path. If the module being read is a package, the
returned dictionary has a key <code class="docutils literal notranslate"><span class="pre">'__path__'</span></code> whose value is a list
containing the package search path.</p>
