# Objets code

Les objets Code sont spécifiques à l'implémentation bas niveau de CPython. Chacun d'eux représente une partie de code exécutable, qui n'a pas encore été lié dans une fonction.

type PyCodeObject

  La structure C utilisée pour décrire les objets Code. Les attributs de cette structure sont sujets à changer à tout moment.

PyTypeObject PyCode_Type

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

int PyCode_Check(PyObject *co)

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

int PyCode_GetNumFree(PyCodeObject *co)

  Renvoie le nombre de variables libres dans 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, PyObject *qualname, int firstlineno, PyObject *linetable, PyObject *exceptiontable)
  Valeur de retour : nouvelle référence.

  Return a new code object. If you need a dummy code object to create a frame, use `PyCode_NewEmpty()` instead. Calling `PyCode_New()` directly will bind you to a precise Python version since the definition of the bytecode changes often. The many arguments of this function are inter-dependent in complex ways, meaning that subtle changes to values are likely to result in incorrect execution or VM crashes. Use this function only with extreme care.

  Modifié dans la version 3.11: Added `qualname` and `exceptiontable` parameters.

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, PyObject *qualname, int firstlineno, PyObject *linetable, PyObject *exceptiontable)
  Valeur de retour : nouvelle référence.

  Similar to `PyCode_New()`, but with an extra "posonlyargcount" for positional-only arguments. The same caveats that apply to `PyCode_New` also apply to this function.

  Nouveau dans la version 3.8.

  Modifié dans la version 3.11: Added `qualname` and `exceptiontable` parameters.

PyCodeObject *PyCode_NewEmpty(const char *filename, const char *funcname, int firstlineno)
  Valeur de retour : nouvelle référence.

  Return a new empty code object with the specified filename, function name, and first line number. The resulting code object will raise an `Exception` if executed.

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.

int PyCode_Addr2Location(PyObject *co, int byte_offset, int *start_line, int *start_column, int *end_line, int *end_column)

  Sets the passed `int` pointers to the source code line and column numbers for the instruction at `byte_offset`. Sets the value to `0` when information is not available for any particular element.

  Returns `1` if the function succeeds and 0 otherwise.

  Nouveau dans la version 3.11.

PyObject *PyCode_GetCode(PyCodeObject *co)

  Equivalent to the Python code `getattr(co, 'co_code')`. Returns a strong reference to a `PyBytesObject` representing the bytecode in a code object. On error, `NULL` is returned and an exception is raised.

  This `PyBytesObject` may be created on-demand by the interpreter and does not necessarily represent the bytecode actually executed by CPython. The primary use case for this function is debuggers and profilers.

  Nouveau dans la version 3.11.

PyObject *PyCode_GetVarnames(PyCodeObject *co)

  Equivalent to the Python code `getattr(co, 'co_varnames')`. Returns a new reference to a `PyTupleObject` containing the names of the local variables. On error, `NULL` is returned and an exception is raised.

  Nouveau dans la version 3.11.

PyObject *PyCode_GetCellvars(PyCodeObject *co)

  Equivalent to the Python code `getattr(co, 'co_cellvars')`. Returns a new reference to a `PyTupleObject` containing the names of the local variables that are referenced by nested functions. On error, `NULL` is returned and an exception is raised.

  Nouveau dans la version 3.11.

PyObject *PyCode_GetFreevars(PyCodeObject *co)

  Equivalent to the Python code `getattr(co, 'co_freevars')`. Returns a new reference to a `PyTupleObject` containing the names of the free variables. On error, `NULL` is returned and an exception is raised.

  Nouveau dans la version 3.11.
