I do exactly this. It prevents a lot of problems by giving one place to look for class variables and comments on them. Setting to None is good, too, since many times if I use one before setting a value I'll get an exception or really bad results that I can easily trace to the unset variable. > I'm not a big fan of dogmatic rules, other than the rule that says you > should make your code as easy for somebody else to understand as possible.
