How to replicate a row of an array with numpy?

Question

I want to replicate the last row of an array in python and found the following lines of code in the numpy documentation

>>> x = np.array([[1,2],[3,4]])         


        

Answer 1

I have test it using following code

    >>> a
    array([[1, 2],
           [3, 4]])
    >>> np.repeat(a, [2,3], axis = 0)
    array([[1, 2],
           [1, 2],
           [3, 4],
           [3, 4],
           [3, 4]])
    >>> np.repeat(a, [1,3], axis = 0)
    array([[1, 2],
           [3, 4],
           [3, 4],
           [3, 4]])

The second parameter seems mean how many times the i-th elements in a will be repeat. As my code shown above, [2,3] repeats a[0] 2 times and repeats a[1] 3 times, [1,3] repeats a[0] 1 times and repeats a[1] 3 times
