# Generator Objects

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`

  The C structure used for generator objects.

PyTypeObject `PyGen_Type`

  The type object corresponding to generator objects.

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.
