stop script without exiting interpreter

[homerobse]

This is a continuation to an old post (http://bytes.com/topic/python/answer...ng-interpreter) that I think a found a better answer.

The question was:
"I'm fairly new to Python and I've lately been running a script at
the interpreter while working on it. Sometimes I only want to
run the first quarter or half etc. What is the "good" way to do this?

Possible ugly hacks include:

- stick an undefined name at the desired stop point
- comment out the last half

I do not like these and assume that I have overlooked the obvious.

Thanks,
Alan Isaac"
