You need to supply the full path to the file (or be in the same 
directory as the file) when you try to run it.

Mostly on Windows you can run scripts from Windows explorer but for 
simple scripts (like hello world) the window appears and then 
dissappears too quickly to see it. You can most easily get around that 
by putting one of:

raw_input("Hit Enter to quit")   # for Python v2

input("Hit Enter to quit")   # for Python v3


as the last line in your script.

You might find that technique easier than using the CMD window.
But the CMD window is better when things go wrong - it lets you see any 
error messages,...
