></a>Note that the
<tt class=
"ctype">PyTypeObject
</tt> for
<code>None
</code> is not directly
exposed in the Python/C API. Since
<code>None
</code> is a singleton,
testing for object identity (using
"<tt class="samp
">==</tt>" in C) is sufficient.
There is no
<tt class=
"cfunction">PyNone_Check()
</tt> function for the same reason.
<dl><dt>PyObject*
<b><tt id='l2h-

class=
"cdata">Py_None
</tt></b></dt>
The Python
<code>None
</code> object, denoting lack of value. This object
has no methods. It needs to be treated just like any other object
with respect to reference counts.
<dl><dt><b><tt id='l2h-
367' xml:id='l2h-
367'
class=
"macro">Py_RETURN_NONE
</tt></b></dt>
Properly handle returning
<tt class=
"cdata">Py_None
</tt> from within a C function.
