[Tutor] Split string and convert to int

[Lloyd Kvam]

I started a reply saying it didn't really matter, but changed my mind.  I should
have sent it.

My main code reviewer doesn't care for map/filter, but does like the
list comprehensions.  I find it easy to see the implied loops of list
comprehensions when scanning through programs.  map is easier to overlook.

Keep your code somewhat consistent and find what works for you.

David Mertz has a lot of useful recommendations in his book:
http://gnosis.cx/TPiP/
Text Processing in Python (a book)

Chapter one covers aspects of functional programming and uses map and filter
quite extensively.  Also read some of David Mertz's Charming Python columns.
