Ahh but you see, you misunderstand how the whole negative-numbers
thing works. You have your syntax wrong. Python was developed by an
accountant, and you write negative numbers like this:

>>> (1)**12
1

And then, because you're raising it to an even power, you get back
positive one. The hyphen is actually an alignment operator, and it
means "left-align this value".
