Add array element. You can add a NumPy array element by using the append() method of the NumPy module. The syntax of append is as follows: numpy. append (array, value, axis). The values will be appended at the end of the array and a new ndarray will be returned with new and old values as shown above.

NumPy support in Numba comes in many forms: * numba understands NumPy ufuncs and is able to generate equivalent native code for many of them. * NumPy arrays are directly supported in numba . Access to Numpy arrays is very efficient, as indexing is lowered to memory accessing when possible. * numba is able to generate ufuncs/gufuncs.
A numpy array object has a pointer to a dense block of memory that stores the data of the array. Basic slices are just views of this data  they are not a new copy. Binding the same object to different variables will not create a copy.
