Python style: to check or not to check args and data members

[Joel Hedlund]

Bruno >> Your email address seem to be wrong. I tried to reply to you 
directly in order to avoid thread bloat but my mail bounced.

Thanks for the quick reply though. I've skimmed through some docs on your 
suggestions and I'll be sure to read up on them properly later. But as I 
said to Robert Kern in this thread, this does not really seem resolve the
problem of setting an approprate level of validation.

How do you do it? Please reply to the group if you can find the time.

Cheers!
