Are you using Wheezy or the latest Jessie, assuming you are running the Raspbian operating system?

Are you running your Python code from a command prompt or in the Python IDE?

It looks like you need permission to set the GPIO pins state (i.e. sudo) but the best answer depends on how you are running the code.

You can avoid that with GPIOzero.

I don't know exactely which system I m using
because I have bought a SD card which already instaled in order to work with an lcd touch sreen without looking for a driver....
and I m trying to run it from IDLE because I don't know any other way to do it

The program wants you to run it with root privileges.

Try starting idle with sudo.

E.g. sudo idle
