Newbie Shell Editor Question

[Kash]

Hi Everyone,

I am new to python. I have just installed it. I am went to the python
website and used it to download python and a beginners tutorial. I set
the environment variables as explained in the faq. 
However when I start idle and run a program from it; I get the
following types of errors; however I can run the same programs no
problem from my command prompt.
Can anyone please tell me what I am doing wrong? I thought Idle was
used to test programs in. I am able to open a new window and write
code, save it and then run that code; but just not if I type it into
the main idle window directly. 
Any help would greatly appreciated, thank you.
