If you want to get the size of other dimensions or the total number of elements, you should use the appropriate array attributes like shape or size. Is there a NumPy function to get the length of an array? You
Use ndarray.shape to get the shape of the NumPy array. This returns a tuple with each index having the number of corresponding elements. The below examples return (2,4) which means that the arr has 2 dimensions and each dimension has 4 elements (2 rows & 4 columns). ...
