[Numpy-discussion] iterate over multiple arrays

Hy everybody,
I'm wondering what is the (best) way to apply the same function to multiple
arrays.
For example, in the following code:
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] )
a = f(a)
b = f(b)
c = f(c)
d = f(d)
I would like to replace :
a = f(a)
b = f(b)
c = f(c)
d = f(d)
with something like that, but which really modify a,b,c and d:
for x in [a,b,c,d]:
x = f(x)
So having something like a pointer on the arrays.
Thanks for your help !
David
