MAX_LETTERS = 25

There is some discussion of adding a const facility to Python 
which would allow you to prevent changes, but heh, you can 
change it in C if you really want to - just not programmaticlly, 
you have to redefine it... :-)

But its one good reason to use the Upper case convention only
for read only variables. At least that way you get a visual 
warning that something strange is happening whe you do

MAX_LETTERS = foo

later in the code.
