[Tutor] Help with an error

[Saad Mabror]

Hello , So i'm totally new to programming and i decided to start with python , i've installed python 2.7 on my laptop (running windows 7 ) at first i started following a begginer's guide and everything was fine . But later i started receveing syntax error  dialogues on IDLE  even if i'm writing just one simple line such as ( print "hello world") . I already tried uninstalling and reinstalling but that didn't work , so is there any possible way to fix this ? Thanks in Advance .
