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.
PyCode_New(int argcount, 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)
PyCode_New()directly can bind you to a precise Python version since the definition of the bytecode changes often.
PyCode_NewEmpty(const char *filename, const char *funcname, int firstlineno)
eval()the resulting code object.
