How to use the googletrans.utils.rshift function in googletrans

def test_rshift():
    value, n = 1000, 3

    result = utils.rshift(value, n)

    assert result == 125

            d = ord(d[0]) - 87 if 'a' <= d else int(d)
            d = rshift(a, d) if '+' == b[c + 1] else a << d
            a = a + d & 4294967295 if '+' == b[c] else a ^ d

            c += 3
