I don't use Numpy, so this is just a guess, plus reading one web page.

According to:
http://docs.scipy.org/doc/numpy/reference/generated/numpy.random.normal.html

the 3rd argument to normal should be a tuple.  So if you want a single
element, you should have made it (1,)

As for checking the 'length of "z"' did you just use the len() function?
That just tells you the first dimension.  Have you tried simply printing
out "z" ?
