I've started to learn NumPy, when I create an array and then invoke the .shape function, I understand how it works for most cases. However, the result does not make sense to me for a single-dimensional array. Can someone please explain the outcome?

array = np.array([4,5,6])
print(array.shape)

The outcome is (3,)

CodePudding user response：

Output tulpe of ints in the "np.shape" function gives the lengths of the corresponding array dimension, and this tuple will be (n,m), in which n and m indicate row and columns, respectively. For a single dimension array, this Tuple will be just (n,), in which n indicates the number of array elements.
