What is the associativity of Python's ** operator?

Question

I was just playing around with the python command line and the ** operator, which as far as I know performs a power function. So 2 ** 3 should be (and is) 8 because 2 * 2 *

Answer 1

Also:

2 ** (2 ** 2 ** 2)

One way or the other, it becomes 2 ** 16.

This is following standard mathematical operations, where: 2³⁴ becomes 2 ⁸¹, instead of 8⁴ and thus is 2417851639229258349412352, instead of 4096.
