Can GPIO.output be assigned to a variable? Raspberry PI

Can GPIO.output be assigned to a variable like light1ON = GPIO.output(18,HIGH) in python? Because when I do this it automatically turns the light on even knowing I didn't call light1ON.

Solution

  • When you do this:

    light1ON = GPIO.output(18,HIGH)

    You actually call the GPIO.output as a function passing it two parameters, and assign the resulting value to light1ON.

    If you want light1ON to be a function either def it as a function:

    def light1ON():
   return GPIO.output(18,HIGH)

    Or make it a lambda:

     light1ON = lambda : GPIO.output(18,HIGH)
