How about:

 >>> import numpy as N
 >>> N.fromstring("1 2 3", sep = " ")
array([1, 2, 3])

or

 >>> N.fromstring("1 2 3", dtype = N.Float, sep = " ")
array([ 1.,  2.,  3.])

If you pass a non-empty "sep" parameter, it parses the string, rather 
than treating is as binary data. fromfile works this way too -- thanks 
Travis!
