How to initialize a variable only one time when program starts

P: 2
For example I have a button and I would like to use it to turn something on and off with the same button.
So I thougt, I would use some wariable which woild keep track of the state, but I can't seem to make it work.
I would need to initialize X to value 0, but that initialization should happen only once when the program starts.

x = 0 -> (this part should happen only when program is started)

if x == 0:
turn switch on
x = 1
else:
turn switch off
x = 0

I found another solution.
I used a ToggleButton and .get_active() method
to get the state of a button.
