    rnd = Random()
    rnd.state = [r_uint(0)] * N
    rnd.state[0] = r_uint(1)
    cpyrandom = _random.Random()
    cpyrandom.setstate(tuple([int(s) for s in rnd.state] + [rnd.index]))
    rnd.jumpahead(100)
    cpyrandom.jumpahead(100)
    assert tuple(rnd.state) + (rnd.index, ) == cpyrandom.getstate()

Example #2

    rnd.state[0] = r_uint(1)
    cpyrandom = _random.Random()

    rnd.jumpahead(100)
