Actually, this is exactly NOT what I want to do. In this case, each 1 byte interger was converted to a 4byte integer, of the same VALUE. What I want is to convert each SET of four bytes into a SINGLE 4 byte integer as it:

a = array([1,2,3,4],'1') a = fromstring(a.tostring(),Int32) a

array([67305985],'i')

The four one byte items in a are turned into one four byte item. What I want is to be able to do this in place, rather than have tostring() create a copy. I think fromstring may create a copy as well, having a possible total of three copies around at once. Does anyone know how many copies will be around at once with this line of code?
