[Numpy-discussion] new question - summing a list of arrays

[Chris Withers]

Hi All,

Say I have an aribtary number of arrays:

arrays = [array([1,2,3]),array([4,5,6]),array([7,8,9])]

How can I sum these all together?

My only solution so far is this:

sum = arrays[0]
for a in arrays[1:]:
   sum += a

...which is ugly :-S

cheers,

Chris
