14 Code objects are a low-level detail of the CPython implementation.
15 Each one represents a chunk of executable code that hasn't yet been
16 bound into a function.
18 .. ctype:: PyCodeObject
20 The C structure of the objects used to describe code objects. The
21 fields of this type are subject to change at any time.
24 .. cvar:: PyTypeObject PyCode_Type
26 This is an instance of :ctype:`PyTypeObject` representing the Python
30 .. cfunction:: int PyCode_Check(PyObject *co)
32 Return true if *co* is a :class:`code` object
34 .. cfunction:: int PyCode_GetNumFree(PyObject *co)
36 Return the number of free variables in *co*.
38 .. cfunction:: PyCodeObject *PyCode_New(int argcount, int nlocals, int stacksize, int flags, PyObject *code, PyObject *consts, PyObject *names, PyObject *varnames, PyObject *freevars, PyObject *cellvars, PyObject *filename, PyObject *name, int firstlineno, PyObject *lnotab)
40 Return a new code object. If you need a dummy code object to
41 create a frame, use :cfunc:`PyCode_NewEmpty` instead. Calling
42 :cfunc:`PyCode_New` directly can bind you to a precise Python
43 version since the definition of the bytecode changes often.
46 .. cfunction:: int PyCode_NewEmpty(const char *filename, const char *funcname, int firstlineno)
48 Return a new empty code object with the specified filename,
49 function name, and first line number. It is illegal to
50 :keyword:`exec` or :func:`eval` the resulting code object.
