Re: error handling in user input: is this natural or just laborious

i'm still in the early stages, and am trying to code something simple
and interactive to get the percentages of the portfolio in the five
different investment categories. i thought i'd get in with the error
handling early so if someone types in something wrong (like a word), or
the numbers don't add up to 100%, the error would be caught immediately
and the user sent back to the start of the loop.

You may want to have a look at the formencode package. While mostly
used in web apps, it's perfectly usable for all kind of
python<->outside world data conversion/validation.
