Cirq - Measure Density Matrix Function Getting First Element

Hello I am using measure density matrix function like that:

for i in range (10):
    measurement_result = cirq.measure_density_matrix(state,indices=[0, 1, 2])
    print("measurement",measurement_result)

And my results are like that:

As you can see, I have ([0, 0, 0], array([[0.36107099-0.36107099j, 0. +0.j , and I want to extract first part [0, 0, 0] (the qubit part) and then I will count how many [0, 0, 0] , [0, 0, 1] [0, 1, 0] … But I could not extract the first part of array. How can I get the first part [0, 0, 0] ?
Thanks …
