I guess this is a numpy question, but how do I do truth tests on arrays? I'm trawling around the documentation but struggling to find an answer..

I want to test if any array contains ONLY zeros.

Originally I had: if a == 0: # code in here

I need this to be true both for a = 0 # ie a is just a number

and for a = array((0,0,0,0,0))

Have a look at sometrue/alltrue: e.g. alltrue(a==0.0) returns True if all elements are zero. Christian
