生成器对象

Generator objects are what Python uses to implement generator iterators. They are normally created by iterating over a function that yields values, rather than explicitly calling PyGen_New().

PyGenObject

用于生成器对象的C结构体。

PyTypeObject PyGen_Type

与生成器对象对应的类型对​​象。

int PyGen_Check(ob)

Return true if ob is a generator object; ob must not be NULL.

int PyGen_CheckExact(ob)

Return true if ob’s type is PyGen_Type is a generator object; ob must not be NULL.

PyObject* PyGen_New(PyFrameObject *frame)

Return value: New reference.

Create and return a new generator object based on the frame object. A reference to frame is stolen by this function. The parameter must not be NULL.
