Code Objects
Code objects are a low-level detail of the CPython implementation. Each one represents a chunk of executable code that hasn’t yet been bound into a function.
-
PyCodeObject
The C structure of the objects used to describe code objects. The fields of this type are subject to change at any time.
-
PyTypeObject
PyCode_Type
This is an instance of
PyTypeObject
representing the Pythoncode
type.
-
int
PyCode_GetNumFree
(PyCodeObject *co) Return the number of free variables in co.
-
PyCodeObject*
PyCode_New
(int argcount, int kwonlyargcount, 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) Return a new code object. If you need a dummy code object to create a frame, use
PyCode_NewEmpty()
instead. CallingPyCode_New()
directly can bind you to a precise Python version since the definition of the bytecode changes often.

PyCodeObject*
PyCode_NewEmpty
(const char *filename, const char *funcname, int firstlineno) Return a new empty code object with the specified filename, function name, and first line number. It is illegal to
exec()
oreval()
the resulting code object.
