ndim - c.
shape - d.
dtype
Solution
The attribute used to retrieve the number of elements in an array is a.size. Here's a step-by-step explanation:
-
In Python, arrays are handled by the numpy library. This library provides the ndarray object which is used to store arrays.
-
The ndarray object has several attributes, one of which is .size. This attribute returns the total number of elements in the array.
-
So, if you have an array a, you can get the number of elements in the array by calling a.size.
The other options provided do not give the number of elements in an array:
- a.ndim gives the number of dimensions of the array.
- a.shape gives the shape of the array, i.e., the length of the array along each dimension.
- a.dtype gives the data type of the elements in the array.
