raspberry pi in a python script

[Raysz]

Hey everyone
so I have this simple function for my raspberry pi
and I made a python file it does work

from gpiozero import LED
from gpiozero.pins.pigpio import PiGPIOFactory

# this IEP address is assigned to raspberry pi
factory = PiGPIOFactory(host='pi's IP address')
Switch_1 = LED(18, pin_factory=factory)
Switch_2 = LED(23, pin_factory=factory)
Switch_3 = LED(24, pin_factory=factory)


Switch_1.on()
Switch_2.on()
Switch_3.on()

But the problem I'm running into
I tried to merge it into another python file
and put it under a function which I called
def raspberry_pi():
but for whatever reason it doesn't work I'm having a hard time understanding why

Under that function I can call the file and it will work
I just can't put everything under the function I don't understand what's going on

Has anyone ran into this problem
