## Solution 1

Numpy ndarrays are meant for all elements to have the same length. In this case, your second array doesn’t contain lists of the same length, so it ends up being a 1-D array of lists, as opposed to a “proper” 2-D array.

From the Numpy docs on N-dimensional arrays:

An ndarray is a (usually fixed-size) multidimensional container of items of the same type and size.

a = np.array([[1,2,3,4], [5,6,7,8], [9,10,11,12]]) a.shape # (3,4) a.ndim # 2 b = np.array([[1,2,3,4], [5,6,7,8], [9,10,11]]) b.shape # (3,) b.ndim # 1

## Solution 2

The first array has shape (3,4) and the second has shape (3,). The second array is missing a second dimension. np.array is unable to use this input to construct a matrix (or array of similarly-lengthed arrays). It is only able to make an array of lists.

>>> a = np.array([[1,2,3,4], [5,6,7,8], [9,10,11,12]]) >>> print(a) [[ 1 2 3 4] [ 5 6 7 8] [ 9 10 11 12]] >>> print(type(a)) <class 'numpy.ndarray'> >>> b = np.array([[1,2,3,4], [5,6,7,8], [9,10,11]]) >>> print(b) [list([1, 2, 3, 4]) list([5, 6, 7, 8]) list([9, 10, 11])] >>> print(type(b)) <class 'numpy.ndarray'>

So they are both Numpy arrays, but only the first can be treated as a matrix with two dimensions.
