Python Exponent Question

[Zero Piraeus]

:

> v = 2
> v**v = 2**2 = 4
> v**v**v = 2**2**2 = 16
> v**v**v**v = 2**2**2**2 = 65536
>
> I would expect 2**2**2**2 to be 256

"... in an unparenthesized sequence of power and unary operators, the
operators are evaluated from right to left ..."

So, 2**2**2**2 = 2**(2**(2**2)) = 65536
