PL/Python also supports anonymous code blocks called with the
<a class="xref" href="sql-do.html" title="DO"><span class="refentrytitle">DO</span></a> statement:
</p><pre class="programlisting">
DO $$
# PL/Python code
$$ LANGUAGE plpython3u;
</pre><p>
An anonymous code block receives no arguments, and whatever value it
might return is discarded. Otherwise it behaves just like a function.
