1) ITYM "scheme" not "Lisp" - not all Lisps require the tail call
   optimization (eg. Common Lisp) .

2) Implementing something tail recursively in Python is liekly to
   lose, as the function call is a pretty expensive operation.  If it
   can be written as a loop, write it as a loop!  If you can't write
   it as a loop, then you'll have trouble writing it tail recursively.
