I want to connect between 1 and 4 lightbarriers to my RaspberryPi, but I do not know how to do the case differentiation in shorter lines (see below). Can someone tell me how to write the following code in a shorter way? Every case written below should do the same.

```
LIGHT_BARRIER_PIN_1 = 24 
l2, l3, l4 = False, False, False 
if config.value("rfu630.lightbarrier") >= 2:
    l2 = True
    LIGHT_BARRIER_PIN_2 = 5
    if config.value("rfu630.lightbarrier") >= 3:
        l3 = True
        LIGHT_BARRIER_PIN_3 = 6
        if config.value("rfu630.lightbarrier") >= 4:
            l4 = True
            LIGHT_BARRIER_PIN_4 = 13

while True:
    if l4 == True:
        if GPIO.input(LIGHT_BARRIER_PIN_1) == GPIO.HIGH or GPIO.input(LIGHT_BARRIER_PIN_2) == GPIO.HIGH or GPIO.input(LIGHT_BARRIER_PIN_3) == GPIO.HIGH or GPIO.input(LIGHT_BARRIER_PIN_4) == GPIO.HIGH:
            pass
    elif l3 == True:
        if GPIO.input(LIGHT_BARRIER_PIN_1) == GPIO.HIGH or GPIO.input(LIGHT_BARRIER_PIN_2) == GPIO.HIGH or GPIO.input(LIGHT_BARRIER_PIN_3) == GPIO.HIGH:
            pass
    elif l2 == True:
        if GPIO.input(LIGHT_BARRIER_PIN_1) == GPIO.HIGH or GPIO.input(LIGHT_BARRIER_PIN_2) == GPIO.HIGH:
            pass
    else:   
        if GPIO.input(LIGHT_BARRIER_PIN_1) == GPIO.HIGH:
            pass

```
