1.. highlight:: c 2 3.. _boolobjects: 4 5Boolean Objects 6--------------- 7 8Booleans in Python are implemented as a subclass of integers. There are only 9two booleans, :const:`Py_False` and :const:`Py_True`. As such, the normal 10creation and deletion functions don't apply to booleans. The following macros 11are available, however. 12 13 14.. c:function:: int PyBool_Check(PyObject *o) 15 16 Return true if *o* is of type :c:data:`PyBool_Type`. This function always 17 succeeds. 18 19 20.. c:var:: PyObject* Py_False 21 22 The Python ``False`` object. This object has no methods. It needs to be 23 treated just like any other object with respect to reference counts. 24 25 26.. c:var:: PyObject* Py_True 27 28 The Python ``True`` object. This object has no methods. It needs to be treated 29 just like any other object with respect to reference counts. 30 31 32.. c:macro:: Py_RETURN_FALSE 33 34 Return :const:`Py_False` from a function, properly incrementing its reference 35 count. 36 37 38.. c:macro:: Py_RETURN_TRUE 39 40 Return :const:`Py_True` from a function, properly incrementing its reference 41 count. 42 43 44.. c:function:: PyObject* PyBool_FromLong(long v) 45 46 Return a new reference to :const:`Py_True` or :const:`Py_False` depending on the 47 truth value of *v*. 48
