Steven D'Aprano <steve+python at pearwood.info> added the comment:

Not a bug, this is due to operator precedence.

It is documented under the power operator:

https://docs.python.org/3/reference/expressions.html#the-power-operator

and in the operator precedence table:

https://docs.python.org/3/reference/expressions.html#operator-precedence

If you want to raise a negative literal to a power, you need parentheses:

    (-2)**2
