Make a NxN array of 1x3 arrays of random numbers (python)

Is there a way to make a NxN array (so 2d array) of elements, where each element is an array of 3 numbers randomly chosen between 0 and 1?

Output should look something like this:

(0.2,0.45,0.98), (0.7,0.58,0.11) ...
(1.0,0.05,0.63, ...
.
.
.

etc.

I've been trying to do this but there must be a more elegant way. Code included below:

import numpy as  np
import matplotlib.pyplot as plt

lat = []

for _ in range(2):

        w = []

        for _ in range(2):
                a = np.random.uniform(0.0,1.0)
                b = np.random.uniform(0.0,1.0)
                c = np.random.uniform(0.0,1.0)

                D = np.array([a,b,c])

                w.append(D)

        lat.append(w)

        if _ >= 1:
                np.hstack(lat)
