<p>Booleans in Python are implemented as a subclass of integers.  There are only
two booleans, <code class="xref py py-const docutils literal notranslate"><span class="pre">Py_False</span></code> and <code class="xref py py-const docutils literal notranslate"><span class="pre">Py_True</span></code>.  As such, the normal
creation and deletion functions don’t apply to booleans.  The following macros
are available, however.</p>
