Norm of a vector

[Chrissy2009]

Hi,
how can I calculate the norm of a vector or how can I extract a root in pyhton?

Sorry, but I can't find any information about this..

Thanks a lot.

You can use the viz.Vector class to get the length of any vector. Here is some code:

v = viz.Vector(0,3,0)
print v.length()
v.normalize()
print v.length()
