I made a simple if-else structure with functions but cannot get proper outputs

Question

def trafficlight(label):

    if label == "tl0":
        pass
    elif label == "tl1":
        print("STOP")

def person(label):

    if label == "pr0":
        pass
    elif label == "pr1":
        print("STOP")


label = "tl1"

if label == "tl0" or "tl1":
    trafficlight(label)

elif label == "pr0" or "pr1":
    person(label)

else:
    print("Keep Moving")

This is my code, there will be more elif but when I checked before continuing, I noticed that I cannot get any output if I write label other than "tl1". No STOP text for "pr1" or no other outputs for other things. Can you help me? Thanks in advance.

Btw, I wanted to create simple autonomous car's decision tree, if there is any easiest way, I'm open for help.

the error was with the or keyword. this code is working.

def trafficlight(label):

    if label == "tl0":
        pass
    elif label == "tl1":
        print("STOP")

def person(label):

    if label == "pr0":
        pass
    elif label == "pr1":
        print("STOP")


label = "tl1"

if label == "tl0" or label=="tl1":
    trafficlight(label)

elif label == "pr0" or label=="pr1":
    person(label)

else:
    print("Keep Moving")
