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.
