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 - PyTypeObjectrepresenting the Python- codetype.
- 
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 value: New reference.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_NewWithPosOnlyArgs(int argcount, int posonlyargcount, 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 value: New reference.Similar to PyCode_New(), but with an extra “posonlyargcount” for positional-only arguments.New in version 3.8. 
- 
PyCodeObject* PyCode_NewEmpty(const char *filename, const char *funcname, int firstlineno)¶
- Return value: New reference.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.
