quick numpy question

quick numpy-related question.

I want to use numpy.arange() to create multiple arrays, and then I want to join these arrays (or individual elements) to the final array without repeating existing elements (create a 'union' from 2 or more arrays or individual elements).
example:

lev=np.arange(0,20,2)
# lev=(0,2,4,6,8,...,20)

lev1=np.arange(0,18,3)
#lev1=(0,3,6,9,12,15,18)

#I want something like...

lev3=lev1+lev2

#WITHOUT repeating elements (i.e., only one '12' in resulting array), i.e., I want:
#lev3=(0,2,3,4,6,8,9,10,12,14,15,16,18,20)

#or, add just a unique element(s)

lev4=lev3+(50,60)

#so I would want lev4 to look like this:
#lev4=(0,2,3,4,6,8,9,10,12,14,15,16,18,20,50,60)

are these types of operations possible using numpy?
How can this be done?

Please help

Thanks,

P.Romero

Use Python set and then convert to numpy
array?
