: Size of the list can be changed while that of the Numpy array can not.The numpy array is memory efficient. i.e takes less space than the python list even though both have the same 7 elements. Numpy is faster . Also numpy supports vetcorized operations while the list does not .ie. operation on the Numpy are applied on all the individual elements.

element is zero. The below code will create an array with 4 rows and 3 columns, where every element is 0, here we will be using numpy.zeros: import . numpy. as np. empty_array = np.zeros ((4,3)) empty_array. An array with all zero elements will be useful at the time when you want an array of fixed size, otherwise, it will not have any value.
