Numpy's speed comes from being able to keep all the data in a numpy array in the same chunk of memory; e.g. mathematical operations can be parallelized for speed and you get less cache misses. So you will have two kinds of solutions: Pre-allocate the memory for the numpy array and fill in the values, like in JoshAdel's answer, or.
