Ah, I see the problem, it's doing -(1**2), you need to put "(-1)**2".
And, that's not a problem for the vector class, it's only because I
modified my copy a little. OK, nevermind then.

Well, when I type "-1**2" into Python, it returns -1. If I run "1**2
+ -1**2" it returns 0. So, is there a bug in Python then? Running
2.6.6 on Ubuntu 10.10.
Removing the if statement from get_angle fixed the angle problem for
me, because of this.

Your mistake basically was that you assumed that -1 ** 2 == -1
which is not.
Hi again
yes, careful with -1**2 == -(1**2) and (-1)**2 , its not the same (and
the ** operator precedes the - operator hence the -(1**2) if you type in
-1**2).
To avoid that, you could use a variable:
a = -1
a**2 == 1
Glad you found out. :)
