append list values to array

Question

I have a list value like this

t=[[1,2],[3,4],[5,6]

and I declare empty array

earr=np.array([])

so I would like to have an array like this

earr=array([1,2],
           [3,4],
           [5,6])

so I used this line to try to concatenate the list to the empty array

for i in range(len(t)):
    earr = numpy.append(earr,[t[i]])

but the output of this array like this array([1., 2., 3., 4., 5., 6.]) how can I make it like the output in the top?
