Numpy's shape property returns the number of elements along each axis of the array as a tuple.

Examples

One-dimensional arrays

x = np.array([1,2,3])
print(x.shape)
(3,)

The , followed by nothing simply means that the array is a vector with 3 elements.

Two-dimensional arrays

x = np.array([[1,2,3],[4,5,6]])
print(x.shape)
(2, 3)

This tells us that x has 2 rows and 3 columns.

Accessing values inside a tuple

Note that since the return type is just a tuple, you can access the actual numbers using [] syntax, like so:

x = np.array([1,2,3])
print(x.shape[0])
3
