While it's great that to teach about lambda and lisp-like programming
I think focusing on list comprehensions is well more worth while,
especially since they're more pythonic and the lisp-like lambda,
filter(), map(), and reduce() are slated for removal in Python 3000.
Of course there is code that exists that needs to be maintained now and
you've done a good job of explaining lambda for newbies so they can do

Taking the approach that lambda, filter, map, and reduce are okay in
existing code is fine, but all new code really should be using lists
comprehensions.  Of course here I am saying this and not following
jj's example of providing a tutorial.  Maybe if I have more time today
I can reply with a list comprehension version of what jj gave.
