What same menu?
1 Click File -> New.
2 Select "Python script"
3 Paste code
4 Ctrl-S to save (give filename first time)
5 F5 to run (Hm... that's not clearly indicated I guess. But it's
              the run key in all Windows IDE's I ever used.)
6 Switch to Interactive Window
7 Read an interpret traceback
8 Switch back and fix code
9 Go to 4

I'm not sure if you installed ActivePython or Mark's win32all.

In the ActivePython help, look at:
ActivePython User's Guide
   What's included in ActivePython

       PythonWin Development Environment

         Keyboard Bindings

           F5 Run

Remember that "real programmer" don't use the mouse unless
they really have to... Typing at the keyboard is much, much
faster.

It does... Switch over to the interactive window, and you
will see the traceback.

All runtime error messages come as exeptions. Reading
tracebacks is fairly clear. I don't think you need to
grok exceptions.

I guess Mark Hammond though it was self explanatory. ;)

I think you will get used to it fairly quickly.

This is where is chokes first. I think you mean L[i]

When the if-statement is commented out like that,
the next line will cause a syntax error due to the
indetation. You can't suddenly have indented code
without if, while, for, def etc.
