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.
|
|
|
|
.. c:type:: PyCodeObject
|
|
|
|
The C structure of the objects used to describe code objects. The
|
|
fields of this type are subject to change at any time.
|
|
|
|
|
|
.. c:var:: PyTypeObject PyCode_Type
|
|
|
|
This is an instance of :c:type:`PyTypeObject` representing the Python
|
|
:class:`code` type.
|
|
|
|
|
|
.. c:function:: int PyCode_Check(PyObject *co)
|
|
|
|
Return true if *co* is a :class:`code` object.
|
|
|
|
.. c:function:: int PyCode_GetNumFree(PyCodeObject *co)
|
|
|
|
Return the number of free variables in *co*.
|
|
|
|
.. c:function:: 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 :c:func:`PyCode_NewEmpty` instead. Calling :c:func:`PyCode_New` directly
|
|
can bind you to a precise Python version since the definition of the bytecode
|
|
changes often.
|
|
|
|
.. audit-event:: code.__new__ code,filename,name,argcount,posonlyargcount,kwonlyargcount,nlocals,stacksize,flags c.PyCode_New
|
|
|
|
.. c:function:: 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)
|
|
|
|
Similar to :c:func:`PyCode_New`, but with an extra "posonlyargcount" for positonal-only arguments.
|
|
|
|
.. versionadded:: 3.8
|
|
|
|
.. c:function:: 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
|
|
:func:`exec` or :func:`eval` the resulting code object.
