Thanks everybody for the different solutions proposed, I really appreciate.
What about this solution? So simple that I didn't think to it...

import numpy as np
from numpy import *

def f(arr):
     return arr*2

a = array( [1,1,1] )
b = array( [2,2,2] )
c = array( [3,3,3] )
d = array( [4,4,4] )

for x in (a,b,c,d):
    x[:] = x[:]*2
    #instead of: x = x*2
                                                                                         
print a
print b
print c
print d
--
