Just a note: most often (at least if you are working with floating point 
values) you want "linspace", rather than arange:

 >>> N.linspace(3, 99, 33)
array([  3.,   6.,   9.,  12.,  15.,  18.,  21.,  24.,  27.,  30.,  33.,
         36.,  39.,  42.,  45.,  48.,  51.,  54.,  57.,  60.,  63.,  66.,
         69.,  72.,  75.,  78.,  81.,  84.,  87.,  90.,  93.,  96.,  99.])

fewer surprises with floating point oddities.
