How do you concurrently run 4 if statements in python?

does anyone know how to run two if statements at the same time in python?

for i in range(160):

    luca.speed = 1
    if luca.pos() > nick.pos() and luca.pos() > bob.pos():
        luca.backward(luca.speed + 2)
    if luca.pos() < nick.pos() and luca.pos() < bob.pos():
        luca.forward(luca.speed + 3)

    nick.speed = 1
    if luca.pos() > nick.pos() and bob.pos() > nick.pos():
        nick.forward(nick.speed + 8.5)
    if luca.pos() < nick.pos() and bob.pos() < nick.pos():
        nick.forward(nick.speed)

I am trying to make these 4 if statements run at the same time instead of one after the other.
