GPIO Reset during setup?

Hello!
I'ts normal that during initial setup in python the GPIO status is reset?
I would like to write a script that checks the GPIO status every time I call it.
Trying it, semms that during:
GPIO.setup(<pin>, GPIO.OUT)
The GPIO will be resetted.
Thanks!

I believe that GPIO definition should be done once at start of the script, then it will be reset just once.
In this case you are setting <pin> as an output.
If you want to check GPIO status, use: |

Ok, but the script is invoked and executed when needed. I need to wuery the GPIO on which a relay is connected. So, during startup it will be resetted, NO GOOD... 
I can in this case have two approach:
1. Have the script always running
2. Don't use python but gpio from cli and bash.
I've used option two, so it works.
I can query gpio status with 'gpio read < IN>' and so write 1|0.
Thanks anyway!

Accidentally I have come across this website and am a little bit asp.net training kochi confused about the details shared here. This post deals with the details regarding the GPIO reset during setup. I want to know more details about it to understand the concept shared here. Hope that the details will be available here soon. |
