Check GPIO state (how to set it up?)

[Lasersocks]

Is there anyway to check a GPIO's high or low state?

I know I could set it to low at the start and assign a variable based on that, but I am wondering if there is a way to ask what a GPIO's state is at any time.

I was hoping something like print(GPIO.output(11)) would tell me whether the state is true or false, but obviously that doesn't work.

Thanks!

You can read the state of output channels using GPIO.input()

Well that was easy, thanks!

I am using GPIO.input() to try and read the pins state and keep reciving "GPIO not set up or setup in wrong direction."

The pigpio Python module will let you read the level of the gpios. It doesn't matter if they are set as inputs or outputs (or any of the other possible modes).
