How explain why Python is easier/nicer than Lisp which has a simpler grammar/syntax?

Not necessarily.  Some problems very naturally lend themselves to
recursive solutions.  Fibonacci's sequence is one.

#!/usr/bin/python

def fib(x):
    if x < 1:
        raise "arg must be >= 1"
    if x == 1:
        return 0
    elif x == 2:
        return 1
    else:
        return fib(x - 1) + fib(x - 2)

Pretty straightforward.  Now try yourself to write the iterative
version.  If you haven't done this recently, there's a pretty good
chance you'll get it wrong on your first try.  The recursive version
is a bit simpler and more straightforward to understand, requiring
less state to be preserved (and mentally retained, if you're trying to
work through the algorithm mentally or on paper).

It's also probably significantly slower, so you'd likely still want to
use the iterative version, unless you're trying to illustrate how
recursion works or care more about writing easily understood code than
performance..
