Optimise initialisation of several np.zeros() arrays of fixed size in Python

I would like to optimise the process of initialising python np.zeros() arrays. Right now I just have a list of them like

import numpy as np

n_elements = 10

a = np.zeros(n_elements)
b = np.zeros(n_elements)
c = np.zeros(n_elements)
d = np.zeros(n_elements)

Do you know how I could make this bulk of code shorter?

I know that

a = b = c = d = np.zeros(n_elements)

Is not an option, since it will be all assigned to one memory slot.

Thanks

>Solution :

You can use numpy directly to generate a 2D array:

a,b,c,d = np.zeros((4, n_elements))
