IDLE's Shell runs your input with nearly identical results as with the 
standard interactive interpreter, including exceptions.

No. You enter Python statements, not terminal commands.

At the Command Prompt window's prompt, such as 'C:\user\you>', enter
python path/to/comment.py
The path shown before the prompt char, '>', is the 'current working 
directory'. Learn to use the 'cd' command.
