Given that this has no self argument, I'm assuming this is not a class
method.

Given that this does, I assume this _is_ a class method.

So are you putting _determinant() inside the class?  If so, you should
either make it method, and invoke it as self._determinant(), or bring it
outside the class into the global scope, in which case your code should
work.

Cheers,
