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