Linda,
If you're familiar with Matlab syntax, you may find this link interesting:

Here another couple of useful links
http://www.scipy.org/Tentative_NumPy_Tutorial
http://www.scipy.org/Numpy_Functions_by_Category
For your specific example, if you want to create a (256,128) array of unsigned
integers:
import numpy as np
a = np.zeros((256,128), dtype=np.uint32)
Note that if you intend to fill the array afterwards with other values, it
might be more efficient to create an 'empty' array instead of an array full
of zeros:
b=np.empty((256,128), dtype=uint32)
