How to generate an array with the same element more directly?

Question

I have an array value of this form

array([0.69])

Then I would like to extract 0.69 to form an array of this form

array([[0.69],
       [0.69],
       [0.69],
       [0.69],
       [0.69],
       [0.69],
       [0.69]])

I feel that my code is very indirectly and requires many operations.

value = np.array([0.69])
np.array([[value[0].tolist()]] * 7)

Could you please elaborate on how to achieve my goal more directly?

I've found that np.full((7, 1), value) is faster and simpler than np.array([[value[0].tolist()]] * 7).
