When asking for debugging help, it is usually a very good idea to
provide as much detail about what you exactly did as you can.
Specifically, if you see an error message, copy and paste the error
message for people to see.  If you are running a set of commands, copy
and paste exactly what commands you are running.

Why is this important?  Because the people who want to help you will
need to _replicate_ the steps that you are doing.  Maybe you have made
a mistake in typing something.  Or maybe you've forgotten a step.
Without seeing what steps you have taken, we can not tell.

Or, in some cases, maybe the software itself is at fault.  Maybe the
problem is something entirely external.  Computers are complicated,
and a lot of things can break.  Again, we can not know that without
seeing the error message you are encountering as well.

So please provide more information.  Otherwise, we can not help you:
we simply don't have enough information!


According to:

    http://docs.python.org/2/library/2to3.html

you should be able to transform Python 2 programs to Python 3 programs
using the 2to3 program.


When I run the program 2to3 on your sample program, everything appears
to work fine.

and the resulting program.py does appear to use Python 3 conventions.


So I can not replicate or verify what you are seeing.
