How to check if an object is a generator object in python?

In python, how do I check if an object is a generator object?

Trying this –

>>> type(myobject, generator)

gives the error –

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'generator' is not defined

(I know I can check if the object has a next method for it to be a generator, but I want some way using which I can determine the type of any object, not just generators.)
