(n^y) /(n^y) = (n/n) ^(y-y) =>
(n/n)^(0)=> 1, at school in math we learn that if n=0, 0^0 is indefined

False is convertible to 0.
Whatever int ** 0 == 1.

Long story here:
https://en.m.wikipedia.org/wiki/Zero_to_the_power_of_zero
tl,dr: One of these things in maths we just agree upon - or not. 😉
Anyway: Python follows this rule, so that's how that challenge gets to its result.

The number is true, so it is 2**0, in math 0 degree of the number is 1
