How do I set a static class variable in C for Python?

Question

According to Python documentation, implementing a class in C for Python can be roughly divided into three steps:

defining the Object (the data impl)
defining the Type (the behavior wrapper)
defining concrete behaviors, and set them into corresponding tp_xx slots

For new function, init function, instance members, attributes, and even dealloc, all of them can be found a slot in PyTypeObject declaration, like tp_new, tp_init, tp_members, tp_methods and tp_dealloc. But there is not a slot like tp_statics.

Where should I declare the static variables and where should I set them up? I searched for the internet but got nothing. Could anyone give me a clue about this?

Maybe you should check out this question.

There is no static keyword in Python, class attributes are stored in class.__dict__.

@avram has mentioned an answer which solved my problem.
But for anyone who found that your static attributes does not get updated after modification, you may check PyType_Modified function.
