Newbies: Re: Returning none

[Paul Prescod]

I want to make the empirical point that I brought up this None issue
when two different co-workers ran into the problem in three different
contexts in one statistically unlikely week. 

#1. a=list.sort("abc"): "None object has no attribute foo" 

#2. alert( print_traceback() ): "None"

#3. Forgetting to return a value.

For experts this is not a big problem. They can diagnose them quickly.
For newbies this is very tricky.	Sort is tricky because it defies
intuition and print_traceback() was especially nasty because this works
pretty much as you expect:

print print_traceback()

(at least you see the traceback)

And then you try to put it in a dialog box and all you get is "None".
This is not the nastiest thing in Python but it is (IMO) a real problem.
