# 코드 객체

코드 객체는 CPython 구현의 저수준 세부 사항입니다. 각 객체는 아직 함수에 묶여 있지 않은 실행 가능한 코드 덩어리를 나타냅니다.

type `PyCodeObject`

  코드 객체를 설명하는 데 사용되는 객체의 C 구조체. 이 형의 필드는 언제든지 변경될 수 있습니다.

PyTypeObject `PyCode_Type`

  This is an instance of `PyTypeObject` representing the Python `code` type.

int `PyCode_Check`( PyObject *co)

  Return true if co is a `code` object. This function always succeeds.

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)
  반환값: 새 참조.

  Return a new code object. If you need a dummy code object to create a frame, use `PyCode_NewEmpty()` instead. Calling `PyCode_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)
  반환값: 새 참조.

  Similar to `PyCode_New()`, but with an extra “posonlyargcount” for positional-only arguments.

  버전 3.8에 추가.

PyCodeObject *`PyCode_NewEmpty`(const char *filename, const char *funcname, int firstlineno)
  반환값: 새 참조.

  Return a new empty code object with the specified filename, function name, and first line number. It is illegal to `exec()` or `eval()` the resulting code object.

int `PyCode_Addr2Line`( PyCodeObject *co, int byte_offset)

  Return the line number of the instruction that occurs on or before `byte_offset` and ends after it. If you just need the line number of a frame, use `PyFrame_GetLineNumber()` instead.

  For efficiently iterating over the line numbers in a code object, use the API described in PEP 626.
