It does work, but it's not what you want to do.

You have two easy choices:

1)  Use the interpreter interactively.  Open a DOS box, type "python"
and wait for the ">>>" prompt.  If it says "program not found", then go
to the directory where you have python installed and run it there.  Once
you have the >>> prompt, type your program in.  It will run each line as
it gets to it.

2)  Type your program into a file.  Give the file a .py suffix.  Open
your DOS box and type "python spam.py" (for instance).  Again, if DOS
complains that it can't find python, take your .py file and go to the
directory where python lives, and type "python spam.py" again.

2) is the most common choice, since it saves your program for later use.


I assume that you put your program into a file, and then double-clicked
on it from Windows. You're not ready to do that yet--you need to have
some knowledge of Tkinter before you can do it correctly.
