One way to do that is

data2 = numarray.choose(numarray.equal(data,0), (data, another_number))

I am not sure this is the most efficient way. If you get other 
suggestions, you can compare them with the timeit module.

But if you plan to do calculations with the data, I think replacing 
zeros is not critical for performance.
