you using rpi.gpio python module requires root privileges. rpi.gpio accesses gpio via physical memory addresses. access physical memory need root privileges allows read other users data.

root privileges start script using sudo, e.g. rather ./script.py use sudo script.py, rather python script.py use sudo python script.py.

if using idle guess you'll have start idle root privileges, e.g. sudo idle.
