Keep formatting changes out of the patch. You can use git gui or some other tool to cherry-pick which lines you do (not) want to include in a commit. That way you can exclude such changes, commit the rest, then revert the unwanted formatting changes to get rid of them.

Follow PEP 257 (in this case, the initial line should be shorter, and the leading/trailing spaces should be removed). Same for other docstrings.

Wellll.... try to follow PEP 257 but also keep in mind that Blender uses those docstrings for the tooltips, and thus they shouldn't end in a period. Stupid, I know...

I thought it was like that in the python interface (and I was wrong).
Just checked in mathutils_Vector.c, there the up axis is Y and the track axis is Z. Should we follow that convention or go for Z as up axis and X as track axis?

Why name it DEFAULT instead of UNSIGNED? And why is UNSIGNED the default value? Not saying that it should be the other one, just wondering about your thought process.

Usually an angle is not signed, you got to define something to sign it. That's why I thought unsigned angles should be the default.

I rechecked and to be honest, I neither knew that the "signed" vector method is only for 2D vectors nor how it actually signed an angle. So I guess I removed it and kept only the "unsigned" angle for now - my bad sorry. Kinda liked the idea of an easy to use signed angle.

So far, when I needed a signed angle, I ended up using a plane. Basically I've used the signed distance (based on the normal) from the plane to the destination of the vector and used the sign for the angle. This is possible with the current system without changes so I guess it's fine.

This could be an interesting design discussion. Not something to do here -- this code is fine. But in general, we have to decide how Powership is going to handle erroneous values. For example,. the Vector.normalized() function I suggested above will simply return (0, 0, 0) for zero vectors. I feel that maybe here it could also make sense to define x / 0 → 0 and return as many usable values as possible.

I actually had a little design discussion with @nathanvegdahl about this, and until we have a 'debug mode' that can visualise where NaNs are produced, it's better to stick to regular floats. So in this case x/y if y != 0.0 else 0.0

And another minor thing: the list comprehension can be replaced by a generator expression for a little bit of added performance and readability:

res = Vector(x/y if y != 0.0 else 0.0 for x, y in zip(u, v))
